Thawne is one of the pettiest characters I know(still not as bad as Dr. C.J. Hatch from Michael Vey)

Given from what Ivory heard, Homelander is easily in the top ten. I was gonna put Omni Man on here, but he actually changed his ways.

Reverse Flash or Homelander

Ragyo, DIO, Carnage, Joker and Thawne maybe evil as shit but at least they don’t try to hide that.

The fact that Homelander is evil as hell while to pretend he is a good person and hero is somehow the most evilest thing he has ever done.
