People can be killed with pretty much anything
Thoughts don't kill people, unless someone has telekinetic powers. Any tangible thing can kill people, and things that aren't tangible generally won't.

Words cant kill you
A single drop of water? (Like a water droplet) I can't think of anything to prove that it can kill you.
If someone can come up with a correct,proven answer to your question, let's find a way to produce it in large quantities and send it around the world, make it mandatory that everyone have some of it every day.
Happiness and love
