which is the most evilest Goneril or Regan

Gonerial is the most evilest of them both. Although they both treat there father bad Gonerial treated him the worst because Lear was living with Regan at first so she atleast cared for him a bit. But in the end Gonerial killed her sister all over a guy which she loved and taught that Regan loved him as well. it is bad that she hate her dad but worst that she killed her sister over a man.
