Marxists only understand one motive for human behavior
The motives for serial murder are visionary (voices in head), mission-oriented (political cause), thrill (impulsive for fun), sexual (impulsive for sex or necrophilia), gain (for profit either monetary or other) and power/control (want to totally enslave someone for sadistic reasons and then kill them).
Marxists only understand the profit motive. Material motives are not one of many motives to Marxists, but the only motive.
