Lolwut? So I don't know your friend and don't like judging but sounds like they had an ulterior motive there....

Regarding time, I think for people like myself who have once BEEN the toxic time-waster, seeing that behavior in other people can occasionally be an annoying painful reminder of my former self. But like am I obligated to be empathetic, since I know firsthand what their thought processes and possible traumas are?
