You did not go through bayonet training? Aim at the gut and yell "Kill" "Kill" Kill" each time you stuck the dummy? You didn't fire at targets shaped like men? You didn't march to candence with reference with what you wanted to do to the enemy?
I did not say there is a formal class on overcoming the taboo, I said that is one of the goals of the training.
It may not even be meant to be realized, but as I reflect back on my training, adding the wisdom of 30 more years of life experience, I can understand now what was being done. (And for the record, I think it is a necessary part of the training process.)
