If everything has a purpose then evil doesn't exist

[BrianSoddingBoru4]

Why does there have to be a test condition at all? God already knows who is going on a drug rampage and who is going to become a philanthropist. What is the point of killing children with cancer when the outcome is already known? 

Applauding the slow, painful death of children as an opportunity for their parents to serve God makes you a monster. You need to know this.

In order for God to be "fair and just" like he calls himself; such scenarios must exist and happen.
God knows the conclusion, but the drug dealer doesn't yet know the conclusion.

No. I'm not a monster. I have M.S that cripples me from driving or even having fun with friends. I'm tortured every moment by symptoms of M.S and by seeing people forgetting me and forgetting who I was. Damn sometimes I feel like a ghost.

Back to the topic:
It's all a test to see what we shall do when faced with disasters. It's like God is seeing our response to these disasters, then judge us each with their deed.

God is also described as 'merciful'. One cannot be both just and merciful (to a large extent, mercy is the denial of justice).

If God knows the conclusion beforehand, what is the point of judging us based on our reaction to disasters? To go a tad further, an omniscient God would know - before the drug dealer in your scenario was ever conceived - how he would turn out. This makes a very strong case that God creates people for the express purpose of damning them.

Being afflicted with MS has nothing to do with you being a monster.
