The game doesn't hold the player to any standards, but I've noticed the way certain enemies are quite fond of monster summoning and mental domination.
The drow summoned non-drow quite to be meat shield quite often, especially sendai.
The slavers mansion in the temple district are fairly drow-like, they trap the lower floor with traps of monster and demon summoning.
Vampires all love to dominate your friends so they attack you.
Liches are more than happy to send people to slow, withering death with the imprisonment spell
All of these enemies are evil aligned, and they're certainly less than compassionate in their use of magic.
So, do you think a good aligned character with a wand of monster summoning, or a few mental dominations is a bit of a hypocrite? It's fairly obvious that evil aligned enemies don't really follow any rules or sense of compassion when it comes to magic, and to be fair there are other games such as prey and dishonored which are much better at letting the player be non-lethal if they choose. Since non-lethal is rarely possible in baldurs gate, what are the less inhumane ways of defeating or killing your enemies? The evil enemies tend to favor exploitation and slow deaths, so is it just a case of doing the opposite of them? Don't use summons, and kill as quickly as possible?
