Of course if you had quoted the full context of your supposedly damning gas quote:

"It is sheer affectation to lacerate a man with the poisonous fragment of a bursting shell and to boggle at making his eyes water by means of lachrymatory gas. I am strongly in favour of using poisoned gas against uncivilised tribes. The moral effect should be so good that the loss of life should be reduced to a minimum. It is not necessary to use only the most deadly gasses: gasses can be used which cause great inconvenience and would spread a lively terror and yet would leave no serious permanent effects on most of those affected."

lachrymatory gas: That's tear gas. To cause a great inconvenience yet leave no serious permanent effects. To reduce loss of life to a minimum. That's clearly not a memo calling for genocide.
