a semi-theoretical question

[SossMan]

$2/$3 NL cash game at Commerce

Hero has about $275 and villian has $235.

Villian has been active but hasn't been caught being out of line. I suspect that is simply a coincidence, but can't be sure.

Hero has AKo in the BB. MP open limp, villian limps on the button, SB completes, Hero raises to $15, only SB folds.

Flop is

Pot is $48.

Hero bets $40, MP folds, villian instantly pushes.

I don't really want to debate calling or folding, simply this:

Should having the Ace of clubs in the hero's hand make him more or less willing to call the all in?
