Is it ok to kill a dragon under these circumstances:
- It can talk.
- It's not hurt anyone, but it is threatening you.
- It's pretty much put you to work.
- It wants gold.
- You do have a slight advantage in that it's in a cave, so it can't get the high ground.
- Fire is still an issue.
That is assuming you succeed. I'll also consider alternatives to killing. Talking probably wont work, it's need for gold is too great.
