Star destroyed magic completely aware the consequence would be never seeing Marco again, and at the last minute as magic was dying even attempted to make it to the Earth portal and never see her family again just to stay with Marco (and Marco attempted to do the same for Star).
THEN their love magic ultimately cleaved Earth and Mewni together and doomed human- and monsterkind, but they weren't aware that would happen at the time. So they did screw over everyone to be together, but not deliberately and destroying magic normally would've meant either their separation or one of the two permanently leaving their home dimension.
