Do not mix up God with Evil
Do not mix up God's Grand Plan with Evil. We humans are capable of doing Good and Bad things, and we're God's creation. So it will only be common that God is capable of both as well.
The whole world God created is perfect. And by perfect, I don't mean most ideal (though we, as His most favoured of His creation, can make it so,) but perfect as in whole and complete. Of course, that involves the Good and the Bad aspects of all matters. Someone was saying things like why God created natural disasters such as Tsunami, earthquakes and cancer in newly-born kids. But if I drop all those thing out, natural disasters, I mean, I can see no other mean for God to punish us in this life for something bad we have done. We as humans do not have the mind or the wisdom to comprehend and the Grand Plan that God has for all creation. Our little minds seem to (always) think that Death is the end of all creation. Well, it's not, but we tend to think it is because our limited measures in realizing things (in other words, Science) never reached that level yet. We still can't make heads from tails in most cases like the vast outer space or the reality behind ghost stories.
I don't know about other religions but we Muslims have a lot of stories in the holy Quran about how some incidents can appear very unfair and unjust in the human eye, but are actually 'effects' of other much earlier incidents. The story of the prophet Mosa (or Mozes in the bible) comes to mind, the one where he takes a trip and loses a whale to find a wise man who's much wiser than Mosa himself. The wise man does three things that appear to the prophet of God as harmful, unjust and completely wrong. But then discovers otherwise later before they part ways. Some could be familiar with this by recalling the word Karma (we Muslims call it Fate or God's well.)
Good or Bad, it has nothing to do with God. Our days living on Earth are but a lifetime test. We only get to see the results once our souls leave our bodies, so it will do us little good questioning it now.
Imagine a world with nothing Bad in it... you can't, can you?
You can fool yourself saying you 'can' but you can't. Human nature, some may call it. Look at the world now, look at Africa, Afghanistan, Iran, Iraq, Syria and others. Look at Palestine's 60 years of killing and suffering. Forget Japan and America's natural disasters, those are tests laid upon us humans from God to see how we will react. But what about the rest of the things? Why is Bill Gates and few others are the richest (when speaking about money) people in the world while many others sleep with the fear of not getting enouph to eat tomorrow? Why are there people who strive and kill for power while all that others want is to live in peace? Aren't those tragedies human-made? Don't say God allowed them so God is Evil. Sure, God created all things but WE are the ones who allowed those things to happen. We can easily set a universal plan across all nations to coexit and share Earth's materials, oil and supplies. Like on human race... but why don't we do so? Human nature. God created us, yes, but then Humans were the only of his creations that accepted to bear the burden of the Mind. Thus, God bestowed Humans with a Mind while giving the rest of his creation Instinct. We can think for ourselves and change bad things to good to better... but we never do.
Why?
Is God really the Evil one in this picture? God created life on Earth, it's up to us to shape that Earth into Eden or Hell.
Those kids who are born with cancer aren't any different than the kids before them who had a silly flu but died also... because, back then, even flu was dangerous. Medicine evolves with Science, but so is illness. In fact, most of our recent illnesses are caused by yours trully. We have thought of million ways to create pollution. World war one and two, factories, car, nuclear studies, you name it. I don't have it for Science, but we're so irresponsible in this time and age, you have to admit it.
So is God evil?
No, God created all things, Good and Evil. A pefect complete world. It is us humans who promoted Evil ever so strongly. It is us who became so selfish and self-centred that we started to blame God for the Evil we created.
