There is too much unnecessary evil in the world - evil being simply defined as treating people in ways you would never want to be treated.
Kind acts in this world often come with a price tag. People often expect you to pay them back for their kindness in some form or another; this is the opposite of Godliness. They'll say, "Remember when I..." or "Don't forget that I..." as if kind deeds are less important than the costs they incur. I should expect this sort of thing as people suffer, offering up a thousand prayers to whichever 'one and true god' they pray to, while constantly sighing in their soul, "Woe is me!".
It is because of God that you suffer. It is because of the costs of your kindness that God has abandoned you and your children - children who learn this quasi-kindness from you. The only true sin is faithlessness. The children of faithlessness are carelessness, murder, abuse, quasi-kindness, violence, greed, reviling, thievery, sexual immorality (treating people like garbage because of how they look), idolatry (refusing to believe what you see someone doing - especially God, and believing something else altogether), and any other act you would never want someone to do to you. A faithful person overcomes these things, even with time.
A faithful person watches God and is transformed in the flesh. The faithful woman who was once deaf will hear God in the land of the living; the faithful man who was once blind will see God while still breathing in the flesh; the child who was once disfigured will stand structured before God as those around them watch their bones, eyes, and muscles grow, straighten and strengthen. The kind acts of the marvelous God are humbling to the faithful. What can you give to God as payment for God's kindness? You can only do what is good for the world; you can only be faithful; this is the only way to glorify God.
If God were hungry, would God tell you? If God were thirsty, would God command you to fetch water? If God needed worship, would God step out of the Garden to inform you? God has been taking care of God for longer than you or I could imagine - you are not required to handle God's business. And if you have insulted, struck or killed a man because you believe you are doing God some sort of favor, you are greatly mistaken - you have proven to yourself that what you worship is nothing more than an idol you constructed in your imagination. You have been faithless, and this has been too much for you, your children, and the world to bear.
A faithful person will seek goodness within themselves. They will desire to create changes within themselves to be more like the God that has been showering them with compassion and restfulness. If your hope is in a book, then you have stumbled across a sad thing. A book can be doubted and thrown in the trash, and if this can happen to your holy book, then what is your faith? A faith that can be easily tossed in the trash is a worthless thing, it is an abomination. It is for this reason that our ancestors endured awful tragedies and have perished, along with the beasts and other animals. The righteousness of God, the word of God made flesh - which are God's faithful people - do not perish. They have been given the promise, the promise of an abundant and everlasting life. In no manner does God require perfection from imperfection (imperfect flesh), but God does require goodness and for us to perpetually seek what is true.
A man who seeks what is true asks himself, "Why do so many millions of brown-skinned children go hungry?" Upon seeking, he will discover that there is more than enough food for everyone. He will then discover that greed and capitalism has conquered this world, turning our garden into a desert for impoverished children to fight, sometimes with violence and treachery, for the items they need to survive. He will discover that people are paid to work to the bone to provide food that is freely given to millions of livestock, but to gruesomely withhold it from millions of brown-skinned kids all because they have little or no money. The greedy then justify their actions by saying, "It's a dog eat dog world", never speaking the more obvious truth that it's a "lion eats gazelle world". The man who seeks, and has become faithful, will then say to himself, "It is not my job to figure out how to get rid of lions, or how to separate the lions from the gazelles, but to figure out ways to end the systems of oppression which create lions and gazelles so that all may live in relative peace and harmony."
