Bad guys have a lot of problems keeping a Nebulous Evil Organisation running. High turnover due to heroic raids, lack of professionalism in the Evil Minions, and motivating the surviving personnel. This last one is especially difficult because just as Evil Cannot Comprehend Good, it also can't understand positive reinforcement. When a minion or even their Number Two (The Dragon) performs well, they won't so much praise their effort or reward their good results as warn them "do not outlive your usefulness". Kind of hard to go to work with a smile with that hanging over your head.
