I mean... personally, I do not find her kinda cute, but I realize that everyone has different things in different combinations that make people appear attractive to them.
I do totally agree that it should not be the case that an arguably adorkable looking person should be mocked and treated cruelly for their looks alone, but also, I graduated high school not too many years before she did... and well yeah, high schoolers are very often demons with skin suits.
Also... her wiki says her family, her upbringing was pretty violent, and her brother has/had schizophrenia.
So... having been around schizophrenics myself... yeah that can be basically maddening.
I agree that it is a tragedy to some degree, but I feel like that stops mattering as an excuse or explanation when you start to do as much and as significant broad (and direct) harm as she has done.
On the other hand...
Darkness cannot drive out darkness, only light can do that. Hate cannot drive out hate, only love can do that.
