I remember seeing this a a boy. The main guy was a scientist. I think he was working on an adaptive suit or possibly a cyborg. He becomes the prototype. I do not remember it all but I know if he is touched he gets defensive automatically and he cannot control it. There is a battle between him and another cyborg like himself. He loses power and at the end, shows him in a displaycase.
The Vindicator (1986)
An employee of a secret company operation becomes the victim of the company's special weapons project. He is transformed into a robotic killing machine that, because of his programming must destroy anything that comes near him. source
I remember watching this movie: The main character, Carl is a scientist in a robotic company that also works on a behavioural conditioning, that turns even mildest creature into a violent killer when touched (early scene shows a chimpanzee that turns suddenly violent when touched by a toy truck). Carl's boss Alex arranges an accident in which Carl is officially killed - but in truth Carl is turned into a cyborg with the "kill on touch" software. Carl manages to escape in a garbage truck, but he gets severely damaged by incinerator (for the rest of the movie he keeps constantly loosing white "blood").
