"You cannot do wrong and feel right. It is impossible." - Ezra T. Benson

I believe that nothing is impossible. Why? Because no matter how hard you try you cant ever just not come across some sort of logical explanation. There is, however a variety of exceptions. This would be an example of one because it all comes down to a person's own values and morals and where they come from or perhaps the way that they were raised. The only reason as to why you think something is wrong is because you were taught to believe that it is. What might be wrong to you, might be completely normal for some one else who comes from a whole other world than you do. You can't just feel bad for something you are doing wrong because at the end of it all, is it really wrong? There is a million things that one can think of as impossible and a million more that could be wrong or right, but it is up to the person to create a perspective of their own and to decide what really is "wrong" or "right" in the world. It is up to them to choose how to feel about what they have done and to decide what to do next or they want to keep doing wrong or good. If someone feels bad about something, then they chose to feel that way because they are in control o their own thoughts in feelings. Some people are just unaware that they have self-control.
