There are several terms we use as descriptors as if they are an absolute condition or state of being. Some of them are misleading insomuch that they seem to be on equal footing with their supposed counterpart.
Take for example the term dark, when used in reference to a room or the night around us. Dark is not a true measurement. There are no units of dark. There are only units of light. We measure light and use the term dark to describe the absence of light. Dark is solely a term of relevance, describing a condition where someone feels there is sufficient absence of light. Cold is another term like this. We measure units of heat and we say something is cold when it reaches some level of an absence of heat.
To refer to something as wrong is similar. When we refer to something as wrong we are describing it as being absent of or deviating from the condition of being right. Right is the standard. When we say something is wrong, we mean it does not or is not at the time, living up to the standard of being right. Whether we want to accept it or not we all have within our natures some level of understanding of an absolute standard of right. See my previous articles on God and intelligent people along with the article discussing other gods for more background. When we talk of something being wrong, or unfair, we are measuring it against this standard that originates with God.
Wrong is not an alternative means of doing something. It is the choice to deviate from the right way or the standard.
