@parados,
I have never said that killing was the only way to defend yourself in an attack.
BUT, when you are attacked, you have every right to use deadly force to defend yourself.
But in my opinion killing your attackers is the best way to defend yourself, and society at large.
If these 2 animals that attacked this old man had been killed by him, it would have been justified.
When you choose to attack an innocent person, you choose to accept the consequences.
Up to and including death.
