Either they think they are the baddest guy around, which will eventually be wrong, or they worry about what others will do. Destroying a biosphere is not a quiet event. Anyone with the ability to do so also has the ability to monitor for that. So if you take out someone else you make yourself a target.
Not if you redirect a few comets. Depending on what their travel to and from looks like, we might not even notice an alien ship setting our destruction into motion.
