Is it justified to kill people to prevent them from killing animals?

Both Animals and People are equal to the nature, although personal interpretations of personal God(s) may state otherwise.

Science seems to consider that People are Animals with ability to think advanced ideas. Birth, Death, existence, feelings, etc are same in nature.

For example:
1. U.S justified in launching a pre-emptive strike at Iraq to prevent Saddam Hussein to use assumed weapons of mass destruction (nuclear, chemical and biological weapons)

2. U.S. invaded Afghanistan after the 9/11 demolition of U.S. asserts to prevent assumed Al Kaida terrorist organization to assume enslave the People of America.

3. 'A' shot at 'B' to prevent 'B' from shooting at 'A'.

Is it a Fallacy to do Two Wrongs to Make a Right?
