Well, those could be extremities impossible to justify, as Orleander's colorful examples illustrate. But in a more sensible situation, opinions are simply extensions of a particular mindset, and a mindset dwells from a particular outlook. However, those mindsets are oftentimes also dependent on other factors, such as compromise, economy, advantage. All those things change somewhat when society's plugs are no longer connected, right? So then, "wrong" takes on a whole new feel, no?
It all has to be related to the one person. Its only wrong if its deemed wrong by the person. As there is noone else there to decide about wrong or right. Ofcourse if the person has been brought up in a society like ours he will be programmed with whats right and wrong. In that case, although the person is raping and torturing animals, the person knows that what he/she is doing is wrong (according to his/her upbringing). On the other hand if the person has never been in contact with any sort of morality the person wouldnt have a clue about wrong or right, apart from the persons own ideas about it (assuming the person actually took the time to think about the morality of his/her actions).

A sense of right and wrong doesn't just come from society programming. It first starts with your sense of self-preservation and as you come up against things outside of yourself, you learn they have the same need and so find ways to mutually respect it. If you are by yourself then the only one you can harm is yourself which technically could be morally wrong as its self-destructive but then it's your life and no one or thing is going to be affected by what you do. If you are talking about one human being with no other life on the planet. Even abusing animals, you will come across defense and even eventual attack by them. For those that can't, still technically it is morally wrong because though they can't defend themselves, the actions go against their best interest and would not want you to harm them.
You are predefining "self-destructive" as morally wrong. Whos to say ?? Please Register or Log in to view the hidden image! Please re-write this part and use better sentences.
It would depend upon what that persons judgments were as to what was right or wrong to themself. He is the only person alive so he would be the only one who knows what he thinks of right and wrong. That being said who cares for there's no one to judge him as to what he does.
Unless there is a religious imperative. If we put right/wrong into a religious context, for example to that of Christianity, then he certainly could do right and wrong -- just not to other humans. However, he would still be judged by God based on his actions.
