How can you analyze these kind of situations, if its profitable or not to call here?

U are Not doing well Against Draws.
U are Not doing well Against Ax.
U dont Even have a huge Edge Against KQ Meaning a pure Bluff.
People are Scared on A High usually and won't Play back especially on A High.
People tend to Not play back.
U are crushed vs better 7x.

Is there some evidence that you think he is going to Play back?
For example have you won a Big Pot before or stole a Lot of pots away?

If no then its a clear fold where Not much Analysis is needed.
If yes then ofc you Could Herocall and Show him that you are there, Even if it is Bad, you Show him that you are so Manly and maybe its so Future +EV that he will Never Bluff you again or Always Play straightforward from now on.

This is Unlikely so I fold. You are Not doing well with your Equity.

He was quite aggressive and 3 betted a lot. I thought that he has few aces and his range is weighted towards flush draws and/or overcards.

Overcards are Not possible on The Board you mean overcards to your pair yea.

If he 3 Bet a Lot maybe 3 Bet shoved a Lot then he can still have better 7x and your Not doing too well Against straightdraws and Flushdraws too.

If you had 7K its more likely a call because you beat all 7x that are no 2 pair.
