[quote]Therefore, if morality follows the same abstract and subjective definition that beauty holds, then people can consider anything, nothing, or everything good/evil and [b]there is no logical reason for there to be any consequence resulting from the holding or execution of such a belief[/b].[/quote]

Firstly, laws and a person's morality are very different things. The laws of a society and the morality that a person has who lives in that society are [b]completely different things[/b]. That person may find doing something completely ethical and justifiable but the way that the society views those actions are the guiding factors that in the end lead to his decision on doing them or not, based on if he wants to live in said society. Laws are set for a reason. They protect the rights of an individual so that individual isn't forced to protect it himself. Not everyone has the same views on things or the same morality and so the laws that are set for a specific community serve as a guideline on what everyone should and shouldn't do. In few words they guide our lives to peacefully co-exist with other humans in a far bigger society than what is our family, effectively nullifying the different views that we have on what is right or wrong, things that one should do or do not. 

[b]We don't punish people because what they have done is evil or not, we punish them if they have broken a set of rules in the society that they live, rules that were formed and placed on logical reasoning.[/b]

[b]Furthermore the breaking of these rules doesn't make one "evil" no matter which rule he broke, it just means that that person is a danger for the society in which he lives in and isn't capable of co-existing with said society anymore.[/b]

[quote]If morality doesn't exist because it is subjective, then feeding a homeless person and killing him are equally valid options with no inherent superiority.[/quote]

What you said there is called amorality which means exactly that, that morality doesn't exist, right and wrong are the same with no difference.

Morality does exist, given that it doesn't exist in the physical world it does exist in a subjective manner. As you said, like beauty but different from it in the sense that the beauty that one perceives can not be dictated or have set boundaries placed by others. It is yours to have and enjoy, it is part of an individual and born with him. Different from morality which can be dictated and have someone raised with a number of set moral codes. You were raised as a christian no? As one, you have been raised with a number of moral codes by your family/guardian that you have learned to live with and live by. You can't treat and dictate the concept of beauty within a person like that. You can say to him "this painting is ugly" every single day of his life but if that person really likes that painting he will still go on to like it til the end.

Morality, unlike beauty, is the deciding factor on our actions. Once again I repeat, it is different from laws, which if broken there are consequences, in the sense that it is subjective and if you break your own moral code, the only consequence(other than the law if you broke it) is your conscience, all subjective. But that doesn't mean it doesn't exist. It very much does and it is there with a very important guiding influence on every action that we take. We could follow moral codes set by the ones who raised us, formed by ourselves based on past experiences or even just to to fit in with the environment that we are in [b]but they do exist[/b], even if not in the physical world.
