That's not Makith. I beleive that's just a regular goblin warrior from our rank'n file. Makith wears a hooded black robe while that dude is wearing basic tribal cloth.
Tinkerer seems to have rule that any NPC that is required to complete a quest is not gonna be killed. Makith gives us the Spirit Potion quest so I reckon she will be fine. Same reason why Bhrute is the only one who survives the King's raid on the village, he is needed to learn Mighty Blow & some of us might not do that before the raid happens.
If the character is needed for a skill, part of a number of different questlines that can overlap or is a girl we have reached pregnancy stage with I beleive they are safe.
You can also see this in effect with Julia & Molly. Julia is persuable as a sexual partner so she will survive the raid & begin a new life with MC on the Family Farm. Molly exists to birth Taurus' child, nothing more. She & Taurus have no quests or skills to teach MC outside of their encounter in the quest "Monster Hunter". So she dies cos she lived her purpose.
Same with Victoria & the Mayor. The Mayor may give u some side quests & play a minor role in some other quests he is not importent BEYOND the The Election. So Victoria easily replaces him in all his quests because it dosent harm the game. But Victoria is a pursuable female so she must life.
