Besides all these vices, they eat the intoxicating Siberian toadstool in inordinate quantities, and this habit alone will in time debase and brutalise any body of men to the last degree.

Is it true or untrue that long habituation to the seeing or inflicting of pain and death, that the mere sights and sounds of the trenches tend with time to brutalise men, and will make them callous when they return to civil life?

I want to apply discipline to the brutal, not to brutalise the sensitive.
