Question: When Evil is walking down the alley, why did Jerry chase after him? Evil didn't believe in the existence of vampires, so he wouldn't have been a threat to Jerry at all.
Question: Reverend Lowe says that he's been killing people because of the sins they committed but why did he kill Brady? He never committed a sin.
Answer: Firstly, Reverend Lowe is deluding himself by saying he only kills people because of their sins. He is in fact wracked with guilt over his actions and has at least one vivid nightmare about this. Secondly, in the Christian faith all humans are considered sinners so this gives Reverend Lowe a justification for his beliefs. Anyone he kills would be a sinner in his eyes, including Brady.
I think the first part is more accurate. It really has nothing to do with the idea of original sin or everyone being a sinner since he states he only punishes the evil, corrupt, and immoral. He tells Marty he'd never hurt an innocent child. He just really has no control of his Wolf side and is lying to himself about why he kills.
Question: Is Tommy supposed to be the "next" Jason? I'm really confused by the ending.
Answer: Yes, originally Tommy was going to be the new Jason. But the makers decided to go in a different direction for part 6.
Question: What was up with the coach's death? Was Freddy trying to rape him or something?
Answer: I think the coach's death was a play on his character being at a S&M bar. People who frequent those places are usually into bondage and being dominated. Hence being tied up, and whipped with the towel. It also fits in with the homoerotic subtext throughout the movie.
Answer: Peter's odd behavior at Jerry's house made Jerry suspicious. When he discovers the shard of the mirror on the ground he finds out why Peter was spooked: Jerry doesn't cast a reflection. Jerry then decided that Charley's friends must be dealt with. In Ed, Jerry sees something which would lead him to believe Ed would make a good servant. Jerry turns Ed into a vampire and sets him against Peter while he himself deals with Charley and Amy.
