I know Bryce has done some awful things throughout the series. But in Season 3 he really tried to become a better person before his death.
1.He helped Justin with his debt and Seth
2.He stood up for his mom and Tyler
3.He tried to make it up to his mom
4.He even made an apology tape confessing all he's done
And he's basically a tragic villain cause his parents were not around most of the time and on top of it all they were getting a divorce.
So please remove him from the Pure Evil category. A Pure Evil villain doesn't express regret or remorse but Bryce did.
