It could also be due to a sense of ownership.

He may want to control Percy to use his abilities for his own goals, like in the original story where Luke has his own dark motives. Also, it could be out of envy. Percy has things that Luke might feel he lacks, so his possessiveness could be a way to try and take what Percy has for himself.
