If determinism is true then no one is responsible for their actions. People who murder, rape or pillage are just as innocent as anyone else because they have no control over their own actions.
Personally I don't believe in determinism. At least not in the sense that all acts are predetermined. Now I do believe in another type of determinism. For example, it's been determined that we will have a free will and we have absolutely no control over that. So we have no free will to stop having free will.

Believing in determinism can be a bad thing. For one thing, if a person believes that everything is predetermined then a person could go out and do anything at all imaginable and not feel the least bit guilty about it. After all, it must have been predetermined right? In other words, it wasn't really their free choice to do whatever they did.
I personally don't believe that. I believe that people can genuinely choose how they will live out their lives.
Besides, I thought that with the discovery of quantum randomness indeterminism was the "in" thing.

Why would anyone believe in determinism? Didn't that go out with Newton's clockwork universe?
