Often times when you leave 2 troops, the territory will be attacked anyways and you will lose an additional army.
Additionally, if you surround your stack with territories you own, you will limit your attack options.
Basically, best case scenario is that you kill a couple extra troops from a random opponent or cause them to take a different location, worst case scenario, you lose an additional army.
In an 8 player game, the cost of inflicting additional casualties on one opponent is generally outweighed by the benefit of having more armies on your stack and more directions to attack to.
Think about it this way, If you were to kill 2 additional troops from one opponent at the cost of one of yours, the other 6 opponents would have an advantage vs both of you.
