Killing and fighting aren't things we should do on a neutral ground but because one has so much money, we might be inspired to do so since we have the money to get of the situation if things get out of hands.
Such money with attract enemies, family friends, gold diggers and many others. One just have to be very careful when dealing with people.
That's just it, such money collected and doing those things will bring fight and even lack of peace of mind.
