The reasoning that has allowed me to come up with this decision is based upon my own personal values that I have which is if there is something that I can do some way shape or form that will allow me to make a difference I am willing to do it especially if it is for the greater good to be helpful to someone else. By me just sitting by and watching the trolley car and letting them all die would be something that I would physically be able to do because of the heart that I have. Though I am not a killer I would still weigh the options between the two and come up with one person dying is better the all 5.
When this problem was first introduced I had the same decision to pull the switch to save the four guys opposed to letting them all die. But I can say that my reasoning behind the decision has somewhat changed before I looked at the situation as damage reduction and choosing between the lesser of the two but now I look at the situation as being to take into account the right thing to do and what I would want someone else to do for me if I were in that same situation.
