Search Results: kill yourself

So you somehow ended up in a situation where you found yourself surrounded by a group of agressive sports fans, bikers, youth etc and there are 100 of them in a circle around you and getting slowly closer. They are threatning you and saying they will kick you in the balls for fun but not to worry as they won't kill you.

You have a AR-15 fully automatic weapon with 100 rounds. They see you have the gun but continue to slowly get closer to you, you fire a warning shot but that doesn't stop them. You shoot one in the leg but the others continue to slowly move in and close the gap. They remind you that they only want to kick you in the balls and maybe only give you a few punches which won't kill you. They are a well known group you have heard of who have done the same thing to others who were hurt and beaten but lived.

What would you do? And no questions saying this will never happen, this is a theoretical question and want to hear what you would do in this situation.

If the last ever male polar bear was going to eat you and you had a choice between sacrificing yourself to save the species or killing it to save yourself, which would you choose?

In this scenario you have a gun so you could alternatively commit suicide before it eats you.
