villain motivation

So here's an article about an ex-Marine sniper who went on a killing spree and was found on autopsy to have a brain tumor in the region of the brain that affects strong and negative emotions. Tragic in real life, great motivation for a bad guy to become a bad guy...

"Silence Gun" makes it impossible for target to talk

How cool is this? In brief, your target is recorded speaking and then on a .2 second delay, the target's words are played back to them. It so confuses the human brain that the target is rendered unable to dreate coherent speech. I have NO idea how I'll use it in a book, but I have faith I will!
