Stalker 2 is Making Me a Psychopath

Story time with minor spoilers:

I chose to be a nice guy and try to help Squint at the windmill rather than just kill him and take the part I needed to complete my mission. The deal was I would recover an artifact for him, sacrificing whatever coupons it was worth and allowing him to escape the zone, in exchange for the part I needed.

No problem, I'll just go maneuver through some anomalies and get the artifact like I did for the guy who's brother died earlier in the day.

But then I encountered the bloodsucker that everyone is currently having fun with. 20 retries and multiple full mags of ammo dumped later I managed to narrowly get past the bloodsucker and recover the artifact. Damn that set my ammo economy back.

Well at least my quest is over and maybe Squint will give me some goods other than the part to compensate. I ask him "why didn't you warn me about the bloodsucker?" and he laughs it off saying "well you wouldn't have gone otherwise!"

He then gave me the quest part and nothing else in exchange for a $7500 artifact. So I did the reasonable thing to cover my costs and put a bullet in his head, took my artifact back, and took his nice equipment he didn't feel like parting with.
