No, more like:

> If you're evil, you're at least competent.

Incompetent evil exists. This statement is wrong, B does not follow A.

> And if you're evil, you're not bad.

They aren't mutually exclusive, so this is incorrect.

> And therefore, maybe you're actually kind of good because you're at least getting something done

This presupposes that "getting something done" is a positive end in itself, which is not a given.

Each phrase is wrong. It's impressive, actually.
