Those kinds of people are the worst. I've seen a few "do their thing" and it's not a pretty sight. Not only can they kill projects, they spread misery to those around them, almost like a cancer. It's up to management to deal with them, but of course, if management is part of the problem, there's little else you can do. In such a case, you can perhaps voice your concerns, but I usually tidy up my CV because I know I won't be working in a place that tolerates (or in some cases promotes) people like that for long.
