Of course. But there is no such thing as a weapon that will only be used to help people. A weapon's purpose is to harm, not to help. It's how that harm is directed that makes it helpful. By existing, a weapon cannot be only helpful to people.

I disagree, but that's not relevant. Can we get any guarantee about the safe use of this device?
