#though i dont think love is easily attainable for jaime either tbh

[ilynpilled]

i personally disagree. i think this is oversimplifying these characters a bit and reducing their complexity to a single line (as important as that line may be when it comes to characterization). i think all lannister siblings have a very complicated relationship to love. and while i do believe cersei prioritizes power, i dont take her at face value and believe she “doesnt care.” imo she is trying to emulate tywin’s dogma regarding love that she overheard him telling an 8 year old jaime, especially because she despises weakness/vulnerability within herself particularly strongly due to how she is perceived because of her gender. to me all three come off as desperate for love in some shape or form, be it from the self or from others (both more like), especially because of being denied it in important ways as a result of having tywin lannister as their parent, among other things.

Is jealousy-envy a common feature of all three Lannister siblings?

I don't think so. If we're talking deadly sins:

"And [Cersei] is greedy. Greedy for power, for honor, for love." Tyrion on Cersei, Tyrion VI, ADWD

The quote above there is as true of Tyrion as it is of Cersei. Who have far more in common with each other than either does with Jaime. Jaime, who could have any of these things if he put the slightest bit of effort into obtaining them, instead comes to realise it's a different sort of honour he craves - the knightly sort, not mere recognition. (Which is not mere at all to Cersei and Tyrion, who struggle to get shit because of assigned sex and disability respectively.)

All three Lannister siblings desperately want for things that money can't buy them. Other people have those things, but for each I think it's the wanting more than the "other people have it!" that defines them. So greed, not envy.
