I'm trying to find a movie that I watched around beginning of the 90's. I remember a few scenes of the movie but cannot find it on the net.
The movie starts with the hero on a bike traveling in a desert. He then spots something moving on the road side. When he reaches it he find a man laying on the ground with his legs "eaten". The half-man asks for water then he asks to die. The hero gives him water then shots him.
The hero also has a kind of laser gun that grills an animal with one single shot.
He continues traveling and finds a small village, where the inhabitants are frequently terrified by a gangster travelling on bikes and modified cars kind of like Mad Max.
In the movie there is also a military commander who survives an airplane crash and starts to believe after that that he has the right to give life or remove it from whoever he wants. The commander builds a kind of a control room in a cave and manages the village from there.
Around the village, there is also a tribe of some kind of cannibals who also was spreading terror in the village. They seem to be the ones who attacked the man in the first scene.
So the hero saves the village from all these things and continues his jounrey on his bike.
