I try to avoid that sort of thing. I am a soft and sensitive boy, but at the same time my stomach likes to reject what I feed it. Meat is generally safe. I'd rather live off the kill than live an even sicker life than I do.
It is important to remember that guilt, as an emotion, serves no purpose except to limit the theoretical freedom of the mind. Constructs like morals and ethics are all guilt. We cannot fully escape guilt; it is not possible. We can, however, do our best to limit the pointless, limiting guilt that tries to enter our lives. These sorts of documentaries that document things we can't change, religion, both pointless instruments of guilt, and we will be more human if we avoid them. Guilt is not necessary.
