In both these hands the villians range is very polarized between sets and draws. Hand one I actually like raising this turn as you don't know what draw he has, Ahxh, club draw, str8 draw, etc and he can play near optimally on the river.

Hand 2 you raised from EP instead of LP so better aces are much more likely to be in his range as hes less likely to 3bet a10-aq. I would just fold this flop.
