That's what I thought.
I'm not sure Mario Incandenza quite fits, since it seems simply to be his nature to be kind--a sort of holy innocent like Myshkin >>7656236--as opposed to actively engaging in the mental task of empathizing with others, but I'll mention him anyway. He has one scene in particular in which he shows remarkable and un-self-conscious compassion for an otherwise rejected minor character.
Also I like >>7657239 for how Bloom seems to empathise with Stephen in particular, and Quixote's empathy for the disadvantaged.
reading the idiot rn and just finished up the chapter where Myshkin describes how he comforted and removed the desloation Marie felt via the children. I having felt as moved by that from either C&P or the brothers karamazov, albeit they do focus on different topics and i enjoyed them both
