If you saw something bad was about to happen wwyd?
If you were at work, school or someplace and you saw something bad was going to happen to someone you don't like would you stop it or warn them?
If you could prevent it from happening would you stop it.? For example you saw a huge can was about to fall on someones head that you can't stand and all you had to do was say close a door and everyone would be safe. Would you just stand there and watch or close the door?
