One sentence that throws the problem of evil out of the window.

[WinterHold]

The only logical answer is that life is a test, and that hardships are mere trials, to write our worthiness of our ranks in that afterlife.
Which throws the "love" theory out of the window: that suffering is made by God, and he is the lord of everything including reward and suffering.

I asked this once, and almost every other religious person on this site said life is NOT a test.

If you think it is a test, then can you answer why some people seem to have easier tests than others?  Like, one person might have a pretty uneventful life, live to be 90, rests easy in his faith, healthy loving family etc.  And another guy has his whole family murdered in front of his eyes, or has his children die of starvation.  

Also, do infants and small children get the same test, even if they die very young?  Like is it a test for the 6 year old who died of a brain tumor?  Is that fair to the 6 year old, or to the person who had 90 years of testing?

Easier conditions in life are not a blessing; they make the path to hell even easier.

Wealthy people tend to have luxuries more easily, and also tend to have sin more easily. If you think about it; it's so easy for me to abuse food and drugs and sex if my conditions were better by birth. A good looking person is also more prone to commit immoral acts, unlike a poor person who doesn't look that special.

Eventually; everybody is equal. Having it easy makes a person more prone to keep living a sinful life.

I doubt that infants are tested. They don't have proper full minds in my perspective. Their deaths are a reminder for the living to be thankful for the life they have.
I believe God is that controlling.

But I think and believe Islam state explicitly that it's a test:

Sura 67, The Quran:
( 2 )   [He] who created death and life to test you [as to] which of you is best in deed - and He is the Exalted in Might, the Forgiving.
