It is always necessary to understand.
And there is nothing but good to come of it.
The idea that your enemy is all bad, all evil, all stupid is what is peddled to the masses to drum up support for wars. The realities are always different.
I can remember the "gooks" being described as stupid, short, near-sighted, drug-crazed morons hell-bent upon slaughtering everyone they could.
They were very smart, very dedicated, less drug-crazed than US personnel, and selective in who they attacked. They behaved as if they were trying to drive a foreign occupier from their homeland. The rest was propaganda.
Never believe your own propaganda. And try to understand why these things happen. If nothing else it will make you a better opponent.
