What do I do???? Lordoss

I was collecting components and, of course, cigarettes; I managed to gather a good amount by going after printing resins and credit. Of course, as always when you have a bunch of cigarettes, you go to your tank buddy who can smash your head like a tomato and is addicted to cigarettes. But well...he told me he wants to get up, that he wants to be helpful and make new memories, and he asked me to help him up, and now...I have the option of taking bayonets.

But I don't want to do that!! With any serious injury like that, you can't remove the sharp object without having a way to close or prevent the wound from getting worse, and that probably applies to him, Knowing a little about the depressing and misfortune-filled world of Forever Winter, I'm going to kill him...is there any way to keep him alive?
