I need help with understanding the responses to the problem of evil and the issues that each face?

I'm not totally clueless to the topic i just get confuesed sometimes.

Feel free to correct me if i get anything wrong or help me bust what i know.

five responses to the Problem of Evil and the resulting issues that

each of these replies face.

1. Evil is punishment for our sins

i don't understand this one at all

2. Counterpart – Can’t have good without evil

if there was no evil there would be no good either

3. Contrast – Can’t know good without evil

If only goodness existed it really wouldn't be appreciated. Goodness is only appreciated because humans know what it is to live without it

4. Natural Law Theodicy – Pain/evil is necessary in the workings of the world.

this one is very confusing

I know that it is split into three parts. freedom, the after life, and other beings with free will (i think)

5. Good Soul Making – pain/suffering builds character and makes you worthy of heaven
