The old "do the ends justify the means" argument. You'll get tons of snooty ethical people in here that pretend that they wouldn't steal candy from a baby in order to save 100 human lives. Well, I'm not one of them. Yes, I would steal candy from a baby in order to save 100 lives.
Where I draw the line depends on the circumstances. I would not kill 100 people to prevent candy from being stolen from a baby. I will only break minor ethical/moral/legal rules and only if it means major ethical/moral/legal gains. And I would do that IF AND ONLY IF there was no ethical/moral/legal way of doing it.
