I agree with others that bring up the point that it makes for a more interesting story. Also time and time again you see stories where the moral is that power corrupts people but in a way with Kamen Rider its like no power doesn't corrupt even if it furthers evil intentions its just that power itself is neutral in alignment and it depends on the person themselves if they use it for good or evil. At least that's how I see it.
