Oh, no problem! Umm it's.... complicated? lol. Chara is a pretty broad subject...... I think they were a very troubled kid who, in all honestly, probably wasn't very good to Asriel as a friend or a sibling. They could be pushy, violent, and manipulative. They loved Asriel, as much as Asriel loved them, but sometimes that isn't enough, and who knows whether they intentionally poisoned Asgore or not, or why they laughed about it later.... it's been common to justify or try and explain Chara's more questionable actions as misunderstood or taken out of context, but tbh I don't think we actually need to do that. I don't think, even in the worst case scenario where Chara purposefully hurt their family at every moment we see it, that makes them a demon, or irredeemable, or that they even NEED to be redeemed. At the end of the day, Chara was a child who committed suicide- whether the intended outcome was to free monsterkind or to destroy humanity, or just to die. Even with the least charitable interpretations taken as gospel, shouldn't they still be worthy of love? Isn't the whole point of Undertale that anybody can become a friend and be understood, if only you reach out to them?
(I'm also a firm believer that Chara is the narrator no matter the route, which informs a lot of their personality to me, and also means that we get to decide their arc as a ghost. That makes way more sense to me than a story like this just going uhhh yeah that kid was pure evil the whole time or whatever lol.)
