It is
always better to be wishing you were in the air after deciding not to takeoff then it is to be in the air wishing you were after the ground after not thinking about the factors that are going to effect the takeoff and subsequent flight........
Even if the pilot was so foolish as to not take into account the many adverse factors effecting his takeoff, during the takeoff roll the aircraft was screaming at him "I can't fly in these conditions". Like an earlier poster said when the aircraft settled back on the ground after refusing to accelerate he still had room to abort the takeoff...but he kept on going
This is past just bad decision making, it is actively choosing to be stupid......
