We pay college professors for their intelligence and for many ( certainly not all) they remain intelligent even when they are not in the classroom. We pay teachers to teach and many teachers (certainly not all ) teach 24 hours a day. We pay construction workers to work hard and get dirty and even after the day’s work is done many (certainly not all) will have dirt under their fingernails. How is it then when we reward pro football players with outrageously large sums of money and public adulation for being violently aggressive on the field, we then act surprised and outraged when some (certainly not all ) remain violent and aggressive after the game is over?
The idea of unbridled aggression making you unfit for football seems sort of counter intuitive to me. Perhaps a better punishment rather than banishment from football would be to force them to play but without pads and helmet.
Galatians: “for whatsoever a man soweth, that shall he also reap.” Perhaps not a good analogy, but it captures the idea for me.
