3-table tourney, 3rd hand...

I'm trying to get an idea of how to play some hands where I've taken bad beats, but where my odds of winning were only around 50%.

3rd hand of the night in a PP 30+3 3-table tourney, blinds(obviously) still at 10/15. I get AK off in middle position, 3 callers in front. I raise to 60 and get 4 callers, with the guy right in front of me going all-in after previously just calling. I call, and then a guy right behind me calls as well.

What would you have done? Results in white:
<font color="white">First all-in has AJ off, guy behind me has A10 off. Flop has a 10 in it, idiot wins. </font>

I'm not sure if I should be waiting for hands when I'm dominating someone, or if I should be willing to go all-in with even a slight advantage...
Thanks for any help.
