Oh go and read those love notes he wrote to his new BFF, the future hopeful assassin. Thank goodness this guy came forward- while his testimony was probably not needed, it sure sealed the deal for everyone that this man should never see the outside of his cell ever again- no doubt the judge probably wanted to sentence him when the prosecution brought this witness to his attention.
It takes a lot of gall to murder your daughter's mom, pretend it's for the baby's safety, then continue to plot deaths, none to which you plan on partaking in- just like with Krystal, he wanted someone else to do his dirty work while he went about his life and on to his next victim(s) he had waiting.
He probably was raised by a master manipulator and thought he was a chip off the old block. Luckily, he's crumbled. Sick person. I still can't call him a "man".
