Nobody gives a rip what the Catechism says except Catholics. It's THEIR church doctrine, not everybody else's.
Speaking of ignorance of the word, Jesus taught about eternal hellfire, which you've denied in previous posts. It would do you good to read some of what He said so that you don't fall into that error again.

The greatest punishment is an eternity separated from the presence of God. Corporal punishment is of no consequence after death.
"These will suffer the punishment of eternal destruction, separated from the presence of the Lord and from the glory of his might" 2 Thessalonians 1:9
