Didn't Ashfurs mom die in like the first series? I'm pretty sure she did

yes but thats not why hes evil

I understand Ash's pain, but not enough to make him the chaotic villain that he was before his death.

I mean, Squilf was practically flirting with Ash until Bramb got mad jelly and then she was like "sorry I lead you on, I'm in love with my ex still teehee"

And then getting unsuspectingly killed by Holly just to hide the secret had to have made him more angry

I understand the post-death anger

But
(SPOILERS FOR TBC)

To try to eradicate Clan life as a while over even that is kind of like actually psychopathic
