First, accept the Bible on what it says and the clear weight of the evidence is that there is not an eternal punishING.
Second, do you want your children to love you and spend time with you learning about life and the world because they choose to believe in you or would you rather have your kids cling to you out of fear that you will torture them? God is our Heavenly Father and He wants to commune with us but he gives us the option to choose to want to commune with him. If we reject Jesus, then we choose death which is eternal separation from God.
“do you want your children to love you and spend time with you learning about life and the world because they choose to believe in you or would you rather have your kids cling to you out of fear that you will torture them?”
Continuing your line of reasoning: I don’t want to be a parent who would “put them out of their misery”.
