She and Ivy continue to kill and kill over and never learn anything and never listen or care for their victims

where Poison Ivy gets revenge on a man who betrayed her, stole from her and tried to kill her? While also making sure no one would believe her?

I know that these two versions aren’t connected but I feel like this is the most logical answer. She was fighting Wonder Woman at some point and she was strangling her with her tail causing Wonder Woman to have to rip/tear it off in defence. Wonder if she has a scar to prove it and even maybe finds it a sensitive subject to bring up, for laugh factor in an episode or something?!
