I read your article. Animals commit rape, murder, theft, etc. all the time in nature by the definition that we human beings give to those words. This is pretty obvious, and considering that human beings are also part of nature, in a purely biological sense, we are animals. However, human beings are the only animals that are capable of empathy, which is why human beings are the only animals who are capable of rape, murder, theft, etc. Evil (intentionally causing suffering unnecessarily) is an offshoot of empathy, if I know what hurts me, I know what will hurt you. A lion may attack you, eat you while you're still alive, and kill you slowly, but you can't call this evil, the lion is just eating. If a human being was to do the same action, it is evil, because he or she knows what he or she is doing, the human being can imagine the suffering he or she is causing because he or she can imagine it being done to him or her.
Also, I noticed in your article that you included things like cheating as part of immoral acts. This is not really the case. In the case of cheating, it is a breach of a contract between partners, it is not immoral as it is unaesthetic. The only immoral acts are those committed against the self-ownership of another. If I were to punch myself in the face, it is not evil because no one has a higher claim to my body and life than me because no one can literally use my body and life but me. Someone can threaten me and force me to do something, but ultimately the only one that can control my body and life is me. The immoral act if someone was to threaten me to force me to do something, is the threat and the actions of the other person. He or she is attempting to control something through force that he or she has no claim to.
If two partners are in a relationship, they have a contract between them of what is expected out of the relationship. If one of the partners was to decide to cancel the contract, all that needs to be done is to cancel the contract (basically just saying I don’t agree to this deal anymore, we need to renegotiate or part ways). If one of the partners decides to breach the contract, it may be a shitty thing to do, but it is not immoral, there was no violation of the self-ownership of the other person, only a breach of contract.
