Suicide Watch

As you can learn from various people in Rivet City, Mister Lopez is a suicidal resident, who is trying to end his life every single day. You can find him on the flight deck at the top of bridge tower every day from 8:00 - 12:00 and 15:00 - 17:00, contemplating suicide. You can:
 * Help him to commit suicide by pushing him off the deck (you will receive negative karma).
 * Talk him into committing suicide by saying he's pathetic (also negative karma).
 * Use speech to convince him that Ted Strayer needs someone to give him guidance and that Lopez is the one to provide it (you will receive positive karma).
 * Push him off manually to his death (no karma change).
 * Shoot him with a weak weapon (obviously when there is no guard around, mentioned below), so that he runs off the edge by accident trying to get away from you (also no karma change).
 * Any of the options involving talking to Mister Lopez as opposed to brute force or a planned "accident" require a speech skill of 50 to convince him to either live or die.

Reward

 * Negative or positive Karma
