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.
You are assuming that people don't want to be selfish and that everyone wants to live in peace, this is simply not true. People aren't "evil" because they lack knowledge, nor because they are unloved. Meeting evil with love is a great way to get yourself killed or psychologically damaged by someone who enjoys being "evil" and thinks you're an easy target to play with.
From the knowledge that comes from experiencing or learning of great hate, evil, and selfishness comes the knowledge and a newfound appreciation for the potential of great love, goodness, and selflessness; even to the point of giving your life for it. I'm sick and tired of hearing about stories like these:

Only when we no longer see the fulfillment of our greatest desires as being our highest happiness—individually, are we able to move beyond the inherently self-obssessed barbarian that's still within all of us, to a future where at least violence is considered obsolete—collectively.
