[Here's a hypothetical scenario. In Nazi-occupied Poland or France, a Christian is involved in the resistance, getting Jews out of the country before they can be killed. This Christian is identified and captured. He knows that once he is interrogated and tortured, there's a good chance he'll talk and betray the resistance. Therefore, not wishing to put anyone else's lives in jeopardy, he commits suicide. He understands what he is doing, wills himself to do it, commits the act and doesn't repent. Does he still go to hell for trying to save his friends by his death?]

The ends does not justify the means.
