I'm a coward.

You know when you're riding through a high-risk area with a chance of getting punctured by a snipe? Well, when I went to airfield (vybor) I was searching the "bunkers" and at the turn of one of them I saw a guy in a crouching grid doing I don't know what. Out of fear I shoot with my scorpion 61 (I miss all my bullets) why? -because I underestimated dayZ... I didn't think that the recoil of a weapon could be so powerful (since I was in an auto) and also because I shoot like a foot. In short, as soon as the zombies chased me right after I took refuge in one of the bunkers and I disconnected to recover from the adrenaline... except that I felt like a coward for having left right after having missed... so I just went back and I think the guy is aiming at the door of my bunker... what do I do?
