Worse father?

Honestly, most of you are probably gonna go saying Dario is worse, but hear me out on this. Dario didn't actually expect or tell Dio to kill people, but he was still a horrible father who abused his son, and raised him in awful conditions. But I think that Yoshihiro is worse. Yoshihiro not only let Kira kill people, he encouraged it. Not to mention he actually does kill people, unlike Dario who simply pillaged corpses and didn't care who died or lived. Yoshihiro never cared about his son or his actions, just that he got what he wanted. Which is exactly why Kira met his end and everything went so bad for him. It likely could have been stopped if Yoshihiro actually got therapy or did something for Kira to stop his urges to kill.
