Suffering\Hate\Anger\Fear\Selfishness\Conciousness
What would be the remedy of fear, and the selfishness that creates it? Knowledge, but of the value of virtue and selflessness specifically. Therefore, all hate and evil would be a lack of knowledge—an ignorance. This is what inspired Socrates (debatably, the founding father of philosophy) to begin teaching strangers around his community, because he knew that it's a knowledge that needs to be gained thus, taught, to the point where he even took his own life to die a martyr to what he had to say. And the knowledge that the fear that would've otherwise have stopped him from even teaching anything at all would be a selfishness. This is what warrants hate and evil to any degree infinite forgiveness, and why it's so important to teach it the error of its ways, through love. Whether through meeting what you would consider as hate when you're met with it, with love, or exemplifying it via selfless actions. Because some people don't even have the ability to tell their left hand from their right (Jonah 4:11), but we can use the influence of an Earth (what a collection of people are presently sharing in—society, driving cars, holding the door open for strangers etc.) to teach the more difficult to do so; if everyone were sharing in selflessness and virtue, wouldn't it be seen as typical as driving a car is today? Therefore, nowhere near the chore it would be seen as otherwise, considering everyone would be participating in it. And what does a cat begin to do—despite its, what we call "instinct"—when raised amongst dogs? Pant. We are what we've been surrounded with, like racists, they just don't know any better, being abscent of the other side of it especially. And love (selflessness) is the greatest teacher, it renders the ears and the mind of a conscious, capable being—on any planet, to be the most open-minded, thus the most willing to truly consider foreign influences.
"We can't beat out all the hate in the world, with more hate; only love has that ability." - Martin Luther King Jr.
What I have to say regarding all hate and evil being an ignorance is what Socrates (debateably the founding father of philosophy) had to say, as well as the Christian and Hebrew Bibles. I can't speak for any other man made thing being held as unquestionably true via the influences of the idea of a heaven however.
Good thing I clearly wasn't calling what Socrates had to say as unquestionably true considering there being no man made things holding what he had to say as unquestionably true, because what he had to say was to never hold any man made thing as exactly that, especially via the influences of a heaven.
