Alright, but the meat of the question is why do you classify some actions as right or wrong?
right and wrong are human concepts and generally apply to human society
for example, everyone eats to survive. not killing your neighbor, however, is the 'right' thing to do because it disrupts human society and has a negative impact on survival to do so, provided he was a good man. if he was posing at threat to everyone else, perhaps killing him was actually beneficial.
many other 'right' and 'wrongs' are pure cultural creations and are influenced by things such as religion, fear, tradition, etc.
