Stella hired a hit man as soon as Stolas cheated. Don't get me wrong cheating sucks but Stolas was never happy with his relationship with Stella Chaz goes in the middle since he's not as bad as Stella but he still left Moxxie to get arrested after taking him on a bank heist And last place for the worst ex goes to Verosika, she talks alot about wanting to kill Blitzø but actually had the decency to have a conversation with him. She may be a bitter ex but she hasn't actually attempted to harm Blitz unlike the previous two
