I don't think anyone in their right mind hates North Korean citizens. I just wish there weren't anyone who would threaten or harm you just for talking to us.
But yeah man, the world doesn't hate you.
The world feels sad because the world is convinced you're experiencing hardship, and the world would like if you had more food, and more comfort, and less pain.
Many sentient beings extend their predictive modeling capabilities beyond the scope of physical cause and effect which is normally handled by pattern recognition and reconstruction:
When these capabilities are extended to simulation and emulation of other sentient agents' sensory and logic systems, the brain temporarily borrows your own sensory systems in mostly-contained active hallucinations.
In order to better anticipate the actions, decisions, and behaviors of another being, your own memories of what a similar experience from your own life felt like is automatically and subconsciously indexed and referenced, giving you a contextual "flashback" of that memory--albeit "tagged" with the context that it's not literally happening to you again but rather that it MIGHT be what's happening (or may have happened) to the individual you are observing or interacting with.
You essentially "remember" something that you didn't directly experience, fabricated from extrapolations of bits and pieces that you have experienced. Even though it's just making an informed guess, it has demonstrated a great deal of utility, just as all predictive models do.
While that may be difficult to imagine as I've just (admittedly rather unhelpfully, my apologies) attempted to ask you to empathize with what it's like to have empathy... Bear in mind this is almost entirely automatic and we don't choose to do it--not even the organic "augmented reality overlay" effect of literally feeling whatever our pattern recognition subsystems predict another to have felt.
It is, nevertheless, a powerful communal cohesion tool because it disincentivizes interpersonal harm and promotes mutual benefit, which, while not as beneficial for individuals, DOES in fact lead to a population outperforming other populations that don't exhibit this trait.
At the end of the day though it's just a very abstract sensory system. There is nothing morally or ethically wrong with being blind or deaf, neither is there with lacking this sensory suite.
Edit to emphasize another point:
Empathy only attempts to anticipate how others feel but it's not magic, you don't literally feel the exact same thing as them or the same instance of experience even if you both observed the same events.
Recall touching a cold object...
The object itself cannot feel.
But your skin is detecting its own temperature falling.
Even empathy is an individual feeling their own emotions... just in reference to the circumstantial conditions observed in another.
If I see someone step on a sharp nail, my pain is what I anticipate feeling were I to step on that nail;
The relief I wish would come to assuage that pain is PROBABLY similar to what the person I observed is hoping for. I would not want to walk on an injured foot, and I would wish that someone would perhaps let me lean on them while I hobble to a place where I can sit and tend to any harm. Therefore, I offer this to them.
