I don't blame you for considering culling the aggressive pullet. I have two RSLs and at least one of them (I can't tell them apart) would bite me every time I went out to feed them. She/they didn't do that before I lost my second from the top hen a couple of months ago and have since stopped with the new additions but had there not been such a drastic change in that behavior after the new hens arrived, they would have been gone.
As for the question on the true personality of the cockerels vs. obnoxious teenagers, the cockerel I had a few years ago never outgrew being a jerk who was over a year before I got rid of him and my current one doesn't seem to have a mean or obnoxious bone in his body (so far) at 5 months.
