Was Kyle's sacrifice unneccessary?
Near the end of the movie, we see him and Sarah running and hiding from terminator in that factory, when he manages to find them. At first, they seem to be cornered, but they are still able to go up some stairs and there is even some walkway, when you climb up, that leads somewhere.
Surely, Kyle wanted to distract terminator a bit by hitting him with that pipe, to buy Sarah some time, but after terminator bitch-slapped him, I don't think it was neccessary for him to blow him up, thus killing himself in the process.
Terminator was already slow and badly damaged, they could've just run as far as possible from him. I get that this was all done "for the movie to happen", but I am curious about what others think about this?
