Fort Hood Suspect Mulling Insanity Plea

Nidal Malik Hasan, the suspected Fort Hood shooter, that claimed the lives of 13 people and wounded 32 others, is currently mulling an insanity plea. I do not think his request in this regard should be granted. He should not be allowed to plead insanity. He should plead evil, as that is what led him to destroy innocent lives. 

He opened fire on unsuspecting people that trusted him, who were seeking help for their depression and others working in a place they thought they were safe. They didn't deserve to violently die in this manner and as such, the plea should be denied, as his deeds are acts of Jihad.
