If I believed in a judgment God who is truly all-wise, omniscient, and genuinely righteous, then why should I believe that killing these men before they have had a 'chance' to repent would place their eternal fate on my shoulders?

If these men had it in them to potentially repent I would trust that God would know that.

In fact, it's this very type of thing that basically makes the idea of having to repent before you die with no chance of redemption after death basically untenable.

Moreover, if this type of thing were true, then anyone who dies and has not yet repented could easily argue a case to God that if they had been giving more time maybe they would have seen the light.

So this type of thinking fails.

This is why an idea of reincarnation with karma makes far more sense. Not only can no one complain that they weren't given enough time to realize the folly of their ways and repent, but ultimately everyone can be given however much time it takes.

I mean, if the only requirement to get into heaven is to eventually repent and it really doesn't matter what you've done before you've repented, then why limit that process to the mere span of a mortal human life. Just take the same principle and apply it to reincarnation, and then no one can complain that they weren't given enough time to repent.

After all, in the scenario you've suggested a lot of criminals who were killed in the midst of their crimes, never lived long enough to repent for what they had done. Yet, criminals who survive their initial crimes might later have remorse.

So it would be a totally unfair (and therefore unjust and unrighteous) to not allow repentance after death.

Clearly that line of thinking cannot be true because it's not righteous and God is supposed to be a righteous God. So that line of thinking doesn't fit in with the idea of a righteous God. Therefore that kind of thinking cannot be of God.

It's human nature to be judgementel wheather we mean to be or not. Do I eccept everyone for who they are. No, and if I said yes, id be lying to myself. I don't go around verbally expressing my thoughts, but they are there at times. At the same time though. It doesn't make me a bad person either.
