Would you call a foul if it will give disadvantage to the team fouled?

I know you guys go by the book and will call a foul when there's a foul, but would you ever consider the situation before deciding whether to call a foul or play on? I know sometimes for a shooting foul the refs would wait and see how the shot goes to determine if body contacts affected the shot.

But for example a scenario where:

A1 (offense) passes B1 and goes for a wide open layup, B2 sees that B1 lost the guy and intends to go for a hard foul by jumping into A1 without establishing legal position, A1 sees B2 coming for him and spots his teammate A2 wide open under the basket, passes the ball to A2 while A1 & B2 collides into each other while A2 receives the ball, in this case you would call a blocking foul on B2 or play on so A2 can proceed with an easy basket?
