doesn't matter really. All it does is make Amata the new overseer and it makes here hate you.

dont kill him because it will affect a future sidequest.

Dont kill him as it will affect a sidequest that i believe gives achivements/trophies.

If you dont want to kill him then when Amata offers you a pistol just tell her to keep it (she gives it to you later). Then when you see her in the room with the guard and oversear just watch. Dont interupt it.

You always have another choice, you chose the violent one.

Naw you don't lose the bobblehead you get to go back after the Water of life (or somethin like that) quest. But it don't really affect much. I killed him too. I also killed the new overseer when i returned to the vault loll

Well just do as you feel if you really mad just waste him... it has some sort of impact but not that much.

no you dont miss any achievements for killing him

Ok there is a quest later on the game that could have him in it, however if you kill him the replace him with another NPC. You don't need to worry about killing him or not.

All these people saying it ruins the quest are wrong, as I said before you can still get the quest, it's just another NPC takes his place and no it's not Amala. You won't miss any achievments or trophies either, I have a platinum for the game myself.

Yupp same here..

i killed him and still got my plat

If he missed the Bobblehead he will =p.
