An Israeli criminologist explains why for Israeli men, killing Palestinians make them less likely to kill other Israelis because they vent out against Palestinians

This is an incredible statement here: "“I would say that for many [Israeli] males, especially, military service serves as a kind of catharsis for their aggressive emotions, therefore much less of it is being expressed in civilian circles,” Dr. Rattner said."  Military service is a kind of catharsis? Because they get to kill and maim Palestinians which make them let some steam off?
