Consequentialism
Consequentialism is where actions are judges by their result which means that decisions can be determined as good or bag until the result of said decisions has happened. An example of this would be robin hood who would steal money from wealthily people which is a bad thing, however he would give that money back to the poor which mean his inherently bad decision was for a good cause so therefore it is justifiable. This creates a grey area where its hard to determine the line between good and bad. It also raises the question what something goof happened for a large group but its very bad for a small group, or vice versa.
