The classic answer to this is no you can’t; however that is not a completely truthful answer. Since the question is a little misleading I will rephrase it first to: can you be hypnotized to do anything you wouldn’t agree to normally?
Hypnosis is a state of mind that relates stimuli in the environment to emotional and behavioral patterns. It is the unconscious processes that form our understanding of the world and presen to us our options and choices. Hypnosis is not about acting against your will, but is about “massaging” and “moulding” that will to produce specific outcomes. Mostly hypnosis is used therapeutically or in entertainment… but with adequate investment in the process a hypnotist can program a person to behave entirely unconsciously or without memory of the event; which would ease the “will” into doing things one usually “wont”.
Classically therapists claim hypnosis cannot be used to make people do things against their moral code or anything against ones will; however this is only true in a therapeutic sense; and even then is not entirely transparent as a statement.
Hypnosis is an implied process when brainwashing and coercion or torture or social pressure produce unusual behavior.
The point still remains that in order to do so; a hypnotist would be incredibly invested in those outcomes; especially malicious ones…
