Ask the infernalists, "Which verse is correct?"
Bad translations lead to Bibles that contradict themselves. Take the Berean Standard Bible (BSB). Which verse is correct and which is wrong? This can be an effective way to open the minds of infernalists.
Matthew 25:46 BSB
And they will go away into eternal punishment, but the righteous into eternal life.
Luke 3:6 BSB
And all humanity will see God's salvation.
