#i don't think he dislikes megalovania. but i'm sure it also reminds him of the halloween hack which he doesn't seem especially proud of

Until you reach Sans, Chara makes no effort to discourage or persuade you. They just state objectively ‘x left’ or ‘but nobody came’.

There is one point prior to this where they do seem to be a bit more... forceful.

This is right before the bridge with Monster Kid and Undyne the Undying. Notice that this isn't even at a save point. This is the only time the narrator actively intervenes, which is odd because you can still abort the route after this point, either by sparing MK or by not killing everyone in Hotland. Although, I think if you don't fight UtU, you get a "normal" neutral ending: you fight Mettaton EX instead of Mettaton NEO, you don't get the phone call from Alphys, and you don't get Flowey asking why you had to go and mess things up. (Not sure about that last one; maybe the trigger for that is exhausting the enemies in the Ruins, since that triggers Flowey immediately recognizing you as "Chara".)

Either way, it seems like the narrator really wants to make sure you at least fight Undyne the Undying, but for some reason they're not as invested in getting you to fight Sans. Perhaps they simply have more faith in Undyne?

Thinking about it. People have discussed to death and debated over whether Chara was ‘good’ or ‘evil’, and talked about their feelings on fandom’s early tendency to cast them as a villain. But now I’m wondering why a lot of fanworks cast them as a hyperactive little shit who swears a lot, gets mad easily, argues with everyone, and is sassy as hell. 

Sassy and sarcastic I can see if you’re going by Narra Chara. But rude, hyperactive, yandere-esque, and especially the swear words… not so much? 

And yeah, I could make arguments about how hiding their face paints a very shy and quiet image. But I’m not going to grasp at straws from still images. I’m going to use dialogue very few ‘Chara is evil’ believers are willing to argue DIDN’T come from them. 

In No Mercy, which is the one route basically everyone agrees they narrate, they’re direct and to the point and usually distant and unemotional. They’re not yelling that you’re a fucking donkey for believing you’re above consequences and can take back control, or heartlessly ripping into the monsters for being so foolishly naive and weak, or gloating over their victory. They calmly explain who and what they are, and what they want. The few times they do insult you, they use sophisticated words like ‘perverse sentimentality’. When they dismiss the monsters they’ve met until now, they don’t go out of their way to be really cruel and insulting. They remain direct and to the point, and are usually cold and harsh statements of fact. 

Toriel’s check in No Mercy is ‘Not worth talking to.’ They’re not wrong. In every other route, talking does nothing, only persistently sparing her lets you make progress. 

Papyrus gets ‘Forgettable’. Again, they’re not wrong. Very few monsters really take notice of him, most only remembering him in relation to other people. As ‘Sans’ brother’ or ‘Undyne’s trainee’. 

Monster Kid is just ‘in my way’. Cruel, but objectively not wrong. It’s less of a ponted insult, and more how little they think of them. 

For Undyne, the narrator isn’t even particularly cold or disrespectful. In two out of three possible flavor texts, they refer to Undyne as ‘the heroine’. Quite a compliment, and one that isn’t wrong, considering how she’s standing up to a mass murderer and protects Monster Kid. 

Mettaton, in No Mercy, gets similarly positive or neutral remarks. ‘Dr Alphys’ greatest invention’ and ‘Mettaton NEO blocks your way’. He sure is blocking your way. And most of the Underground sure does know him as Dr Alphys’ greatest invention. I guess it could be read as sarcastic, but with the tone of all these other bits of flavor text, it feels more like a neutral statement…? 

And of course. Sans. He probably has the absolute biggest variety of No Mercy flavor text. ‘The easiest enemy’ could be read as insulting, but this is corrected to a more objective statement of encouragement. ‘He can’t keep dodging forever. Just keep attacking.’ Other bits of flavor text are objective assessments of how tired Sans is, how YOU feel, and how dwelling on the flavor text isn’t a great use of time. At no point do they call him smiley trashbag, that comedian, or…anything really insulting. 

At no point do they call ANYONE anything especially insulting. They’re not like Flowey, calling everyone idiots. If anything, a villainous and murderous Chara comes off as more cold and distant. Even the Save Points don’t tell you ‘5 more idiot babies to slaughter’ or specifically demand that you finish everyone off before moving on. Until you reach Sans, Chara makes no effort to discourage or persuade you. They just state objectively ‘x left’ or ‘but nobody came’. 

They just… don’t care. They don’t care about any of these people anymore, not even enough to waste energy on insulting them. All they care about is reaching ‘the end’. (Or one could argue they’re at least trying to act like they don’t care.)

Chara states that they were confused upon awakening and chose to follow your lead. Personally I’m inclined to believe that they’re not lying. They choose to follow our orders to the utmost, even when they do not understand those orders, even when those orders lead them to the edge of annihilation. 

On a final note. It’s kinda sad how Chara’s systematic completionist mentality is cold and horrifying in No Mercy… but in the Winter Alarm Clock dialogue, it’s a funny anecdote of a more lighthearted time which both Asgore and Toriel remember fondly, and a behavior Asriel still continues to emulate even after he stops idolizing Chara. 

Any trait, when taken to the extreme, can become nightmarish.
