I say yes. Like you said in your post, the fact that he will kill anyone that stands in his way means makes the fact that he killed other villains invalid. Furthermore, he also does not show any signs about caring for his girlfriend meaning he only cares about himself.

Overall, I agree. He might not be the worst gang leader in fiction, but he is evil by the standards of the work.
