We all are egoistic, that's why we have wars. Not sure if I'm going to survive, but not going to take sides. Pistols and ammo is not going to save anyone, modern wars are about rockets. If life exists in the universe, then we are the dumbest species. Because we didn't learn how to love and respect each other. We still need to kill others to prove our point, nothing changed for thousands, maybe millions of years.
Divide and conquer, like other animals.
