According the Catechism of the Catholic Church
Since Christ died for all, and since all men are in fact called to one and the same destiny, which is divine, we must hold that the Holy Spirit offers to all the possibility of being made partakers, in a way known to God, of the Paschal mystery." Every man who is ignorant of the Gospel of Christ and of his Church, but seeks the truth and does the will of God in accordance with his understanding of it, can be saved. It may be supposed that such persons would have desired Baptism explicitly if they had known its necessity.
So, I'd say first of all that your question made be based on a false premise. But taking just the words of your question at face value, I'd refer you to 1 Timothy 2-4; Ezekiel 18:23, 32 and probably many other verses.
I'd also suggest that the proper response is no different from the proper response in an earthly context. When some malefactor receives proper justice at the hands of the courts, should we rejoice in their misfortune? Of course not. But we can be glad that their unlawful and predatory behavior will no longer continue, and hope that others who may be tempted toward such behavior may be dissuaded by the example of their punishment.
As to hell being a place of physical torture, again I'd have to say that your question is based on a false premise. The church teaches that,
"The chief punishment of hell is eternal separation from God, in whom alone man can possess the life and happiness for which he was created and for which he longs."
So from the perspective of the saved, basking in the splendor and glory of the beatific vision, such separation is torture, and so those metaphors are appropriate.
For me, the most cogent depiction of hell can be found in CS Lewis' "The Great Divorce". It answers the question I think you're getting at: "How can a loving and good God create clay-footed creatures whom he then condemns to an eternity of torture while they beg and plead for forgiveness and mercy". (Hint: He doesn't) Although Lewis was not Catholic, I see nothing in what he relates there that is inconsistent with the church's teaching. I recommend it most highly, especially if this question poses difficulties for you. It's an easy, fun read, to boot.
