You know, it is not necessary that you even have an intention of killing people to end up killing a lot of them. On any long march you will lose the very young, the old, the handicapped.
If this is a forced march, young, healthy people among the victim group will challenge you with force as they see their grandmothers and their children die. You will then have to kill them.
Next thing you know genocide will have happened.
The Turkish government and the Turkish people feel no guilt over this event since "they did not intend it". That does not mean they are not guilty of an atrocity!
Folks who want to line up all the illegal aliens and march them over the border back to Mexico should be aware that there are ALWAYS unintended consequences for such actions.
