Cheaters should never be forgiven

Cheating is a result of bad judgement. When I said "People make mistakes", I forgot that everyone has a different concept of what a "mistake" is. This whole debate is about personal beliefs and morality. There are no "facts", no "right" or "wrong". In itself, the concepts of right and wrong are non-existent. They are but abstract human concepts that result from the empathy in people. There is no such thing as "truth". I would like emphasize this as we move forward with this discussion. Back to my other point, I define a mistake as a flaw in somebody's judgement. Even if somebody is aware that they are making a bad choice and decide to move forwards with an action that harms somebody emotionally or physically, I still consider that a mistake. Not a mistake in the sense that it was an "Oops! Didn't mean to do that!" moment, but rather a mistake in the sense that it was misguided by that person's lack of foresight and perception. Therefore, cheaters, even if they are aware that committing infidelity will negatively impact their partner, are still making a "mistake". Referring to my other point about Identity, I disagree. If a serial killer loses his memory of committing murder, he is not the same person. He is no longer a serial killer. His intents, his memories, personalities are all gone. He should not be held accountable because he is not the one who committed the crime, it was the version of himself prior to him losing his memory. It is the equivalent of a completely new character coming into creation. This is simply an exaggerated scenario intended to challenge a person's sense of identity. Now back to the main topic. Cheaters do not "deserve" anything. Nobody "deserves" to be forgiven for a mistake they have made. People have the right to make the decision of whether or not to forgive someone for an action they have taken. However, I disagree with the prospect of holding that action against them for as long as they live. The concept of identity I have been attempting to convey to you holds true to this scenario. People are constantly rewiring their brain. You and I are not the same as we were a day ago. Those characters are now different versions of ourselves. However, at what point does our perception and thought process change so dramatically to where we are a different entity entirely? Changes of a magnitude such as these could take place in as little as a year. Therefore, eternally condemning someone for a mistake in judgement they committed is absurd, as doing so is the equivalent of accusing two different people of the same action. Nobody deserves forgiveness, but holding a grudge against someone as long as they live, no matter what the action, is quite bluntly, ridiculous and absurd in my eyes, mainly due to my perception of identity and change. Not only does it hurt the person who you hold the grudge against, you also suffer due to an inability to move on. One of my favorite quotes I've encountered this past week is "The secret to change is not fighting the old, but building the new.". I think that applies to this subject quite well. An inability to forgive leads to an inability to break the cycle of negativity.
