Ok.. you think it's morally wrong. Sure you do. well then answer my question.
If you were given the chance to go back and kill Adolph Hitler before WWII began.. would you?
or how about the 3 men who flew the planes into the trade towers?
or your pick of any of the individuals who've opened fire at a school and killed innocent people?
would you take any of those lives to protect the lives of others?
