$6.5 Stars, AQ facing allin from loose player

[Uniqueuponhim]

This seemed like a no-brainer at the time, but I'm starting to question it. Before this, the guy making this raise had shown down QJo which he called a raise with preflop, and ATs which he called an allin for 800 with preflop. Given his range, and the fact that I was already down 360 chips, should I have called here?
