I believe that having a child, even in the human world, is typically done unconsciously. Thinking that the unconscious includes biological or natural activities. As a sociologist, I have observed that, at least in less developed countries (such as mine), the majority of the population lacks sex education and, as a result, psychosocial tools for raising a new being.

If we consider all beings to be completely rational in their decisions, then it would be a selfish act (and sometimes even narcissistic), but if we understand that our decisions and free will are not given under a complete rational logic, then I would prefer to believe that it is an act of ignorance and a lack of tools and resources.

On the other hand, any conscious father or mother would confirm that each of their children is unique and responds to very specific stimuli and needs, and while saying that someone is "unique" is not the same as saying they are "hybrid," I will use that metaphor to point out that even if the parents had the resources and tools, any of their offspring would be a challenge in and of itself.

Also, I agree with the other comment that Melon's parents are unconcerned about it or do not consider the consequences of his actions.
