Naturally, this stems rather obviously from another thread. In this thread, it appears the argument is made that "doing nothing" frees you from any culpability in a moral matter. What I want to know is, do you agree with this? If some sort of negative event is occurring, and you have have the ability or some small opportunity to prevent it, are you in any way morally obligated to do so? Even more so, if you choose to do nothing and the aforesaid negative event comes to pass, are you in any way responsible for that event's outcome?
