Can love exist without hate?

[CapnAwesome]

Well there is a person who is saying that evil exists because god couldn't make a world where good exists and evil doesn't.
It's illogical he says.
So I wonder is it really logically impossible to create a world without evil in it?
He does believe in god and thinks the girl who was tortured for 44 days and lit on fire at the end will have a wonderful afterlife and justice will be served.
Which poses bunch of other questions like how can god create wonderful afterlife with no evil in it if he can't create a world without evil in it.
And if that's justice why didn't he prevent physically the torture of the girl in the first place? Where is justice in this?

I think he has no idea what he's talking about.

I'd be kind of curious as to what kind of Theist your friend is. If they are the type who believes in either a literal or metaphorical garden of Eden, then they defeat their own argument right there. I think the normal problem of evil question counters that point though, if God cannot create a world with no evil, then he is not omnipotent.
