Was this a good deed?how would u judge this?

Titus manlius torquatus was the leader of Romani's in a war.one day he left the fortress.and said noone makes a move however his son killed the other troops leader and the troop run away. So he killed his son. Was torquatus a good guy?bc I said that's right bc if a normal soldier did it he would be killed.but my ma said he showed he was above all a general and not a human.
