Can love exist without hate?

[Rahul]

Ok he brought this point.
He said that for love to exist evil also has to exist because otherwise we wouldn't be able to tell the difference.
What do you think about this?

I don't know if anyone has pointed this out yet but the opposite of love is not hate. It's indifference.

Ok we progress a little but further.
He is saying that he does not need to justify evil in anyway because justice will be served. Bad people will be punished. Good people will be healed(including 16 year old girls who were tortured for 44 days).
And the only person who does not have justice is me because death is the end.

Is he trying to corner me or what?
I told him my justification is absence of somebody who can prevent evil while he has somebody who can but chooses not to.
Let's see what happens next.

If he's a christian then he is wrong. In the christian faith everyone who accepts jesus goes to heaven and escapes any punishment. Bad person who accepts jesus right before they die has eternal reward. Good person who doesn't accept jesus has eternal punishment.
