I mean, is it really that big a deal? Fans always pick apart why characters act the way they do. Like in Naruto, Pain wanted to change the world through pain, which kinda makes you think. Or how Vegeta started as a villain but had his own reasons. It's just people talking about the story, which happens with any popular show. Idk, maybe it's just me but getting mad over a thread seems like too much.
Honestly, the best move is to share your take and then dip out if it gets heated. I've wasted too much time in those threads going in circles. At the end of the day, everyone sees the story their own way.
Logan's right about just leaving the thread. Some fans act like there's only one way to see a character, which misses the whole point. It just kills the fun of talking about it.
