Ben's experience as Whampire proves that Vladats can peacefully coexist if raised to respect the rights of other sapient beings. If Vladats were born evil then Ben wouldn't have been able to stop himself from killing Hobble and would've enjoyed doing it. The Omnitrix is capable of creating whole individuals with fabricated memories and personalities (which is in itself the Omnitrix's single most frightening feature), so I don't think it would be much of a stretch to create compassionate Vladats using Ben's personality as a template. He did after all give up Diagon's power because he didn't trust himself to handle that responsibility.
