I have been thinking a lot about sociopaths and the criminally insane lately which branched off into me considering is what their doing wrong? (i.e. murdering, raping, lying) or is it only wrong to those who believe it is? For instance, someone could think it is wrong to cheat on a test, or even another person because, let's say they use the money they receive to take that class to support themselves and their grades are slipping, if they do not pass this class, they're out of those funds, and therefore out on the street with no alternate means to support them self. Does that make them any more or less wrong than someone who kills for pleasure? People do things out of self interest, basically they do what they do because they want to and can some way justify it to themselves, and sometimes even to others. It's like saying eating meat is wrong. It is all a matter of opinion, an individuals' point of view.
This slogan basically advocates that since we have advanced enough to be able to live on other foods apart from meat,
then it is our moral obligation to stop killing animals for food.
Do you agree with this idea?
Is it our moral obligation to embrace veganism / vegetarianism?
