Well this one may be a little, strange to some.
My personal take from it is to be sure to know what you are getting into to the full extent. If there are missed details, it may turn out bad for you. Even if you are doing a good thing (for the wrong reasons yourself).

People following will know that i'm not a person to mind the character at the end. This one, is a slight exception to that. While nothing bad is going on (other than the usual outcome) it just does appear like it.
