WHAT IS JASON VOORHEES?
He’s mad because in the first movie Voorhees saw Alice (one of the chicks in the movie) kill his mother. His mother was the one killing everyone that Voorhees was suppossedily killing, blaming Voorhees in the progress. Jason Voorhees later avenged his mother by killing Alice in either the second or third movie. He was “messed up” because kids pushed Voorhees into the lake, knowing he was unable to swim, and left while he was drowning. This wouldn’t have happened if the counslers were watching the children, instead, they were drinking, doing drugs, and having sex. So, Voorhees killed the people at Camp Cyrstal Lake to avenge himself.
