Haha, I'm afraid it's not that type of game
Probably the problem is that there is no direct fight with slavers in the game. You can trick them, you can run away from them, and you can also sneak attack them. And the result always depends on chance and skill level. But for some reason there is no direct fight - only with the guards in the gold mine.
This applies to both the slavers in the desert and the slavers who took over the milk farm.
I assumed that the player is unhappy not with the fact that there is no way to literally kill an enemy in the game, but with the fact that there is no normal combat mode when encountering slavers. That is, if the player encounters, for example, a Wild Cat or an Infected Scientist, he can control the process, use attack and defense alternately, resort to contextual attacks, use magic, and so on. But when encountering slavers, there is nothing like that - everything happens automatically, the player does not control anything. As a result, the player does not get the feeling that he just kicked the bastard's ass.
In addition, in normal combat mode, if you skillfully use combat control, you can defeat even such a strong opponent as Mistira, having a modest level of strength, nimble and resilience. When encountering slavers, you have to pre-increase these parameters, which requires multiple repetitions of the same actions and a significant amount of time.
This. While i do understand that there are more than one of the enemies at a time here, i feel like i don't really have much agency when it comes to trying to solve things with combat strategy. Or bruteforcing through the fight with other stats.
I mean, if i was a powerful mage, capable of evaporating beings with mere touch, capable to easily resist compellment spells against me, wouldn't i try to fry them with the spells i know? Try to run up to me? Enjoy the electrifying experience of magic! Why would i try to fight them with a stat that i'm not best at? Why strength only? Why my character wouldn't try to magically keep enemies out? If i have shock hands, i expect to use them when i'm in danger. Why would i risk my life with a stat i'm not best at? And not guranteed no less.
Seriously, sometimes skill checks feel like an obvious gate that prevents proper roleplay. if i want to fight someone, i expect to be in a combat menu, ready to deliver 100+ dmg with lightning, coming from my fingertips! I wanna be Saul Goodman sometimes. If i don't succeed in fighting, i'll take the L and see where the road takes me. If i don't succeed in completing a skill check, i just reset and try again. It doesn't feel deserved when i lost to one instance of RNG, completely out of my control.
Or root OP really meant that they want to kill people. IDK. I just want some more agency with other stats i have. Resilience; Mystic; Nimble; hell, even Sense - all in combat scenarios.
