It's debatable how much murders he and his crew commited. Some sources estimated the number to reach 200, but only about 40 or so are documented. And I believe most of those murders were ordered by others.

But again, a killer isn't necessarily a psychopath and a psychopath isn't necessarily a killer.



That's exactly the same thing. The definition of a psychopath is that it's genetical and you're born as one. A man like Toto Riina grew up in very difficult circumstances and became involved in the mafia at a very early age. So growing up while witnessing cruel things like murder, torture, etc can do crazy things to you're mind. Eventually, you can get used to such an environment. So that's why I'm not convinced that he really is a psychopath. But like I said, it's likely.
