Yes
Although it is abhorrent it is also necessary and beneficial.
I am not endorsing this kind of behavior generally speaking with any sort of enthusiasm and will certainly not defend individual atrocities or the criminals who perpetrate them.
What I am saying is there is a point to this. There is a lot more going on than simple cultural differences. No one, bar a full blown sociopath, would idly take up arms against their neighbors with the intent of extermination. There is a point of critical mass when this kind of action becomes acceptable to fairly rational John Q. Public. That is why our collective human history involves a lot of genocide.
P.S. I have never been accused of being the "Soft and Fluffy" type.
