just thinking about how theo doesn't regret killing his sister, and never will. theo does not make genuine connections with people, if he makes connections at all. he doesn't have that desire, or honestly the care, even regardless of blood relation. he severely lacks empathy and generally doesn't concern himself with anyone who can't help him get ahead of others in some way. this is why i say he's a sociopath rather than a psychopath. sociopaths are very generally able to form a close attachment to one or more individuals, but are usually also incapable of anything remotely even resembling a normal family life. and compared to psychopaths-- they're actually more prone to rage and violence... which... hello? killing your family?? killing your sister??? she had something he wanted and that's all he viewed her as. her heart. he wanted to be special so fucking badly... and by taking her heart it made him a natural, genetic chimera. which also meant all the perks of being supernatural without basically any of the pitfalls. he had no issue watching her suffer or hearing her beg because he never cared. she was simply a vessel for what he wanted.
