Telling Truth: Do You Care About Their Souls?

So, if you have no problem seeing people burn and melt and suffer uh during their life and after, then certainly you can avoid telling them the truth. But, if you do care about them, then you should tell them Jews are not allowed to go to such events. They're not allowed to have such events. And if they disagree with you, you could simply say, "You're not disagreeing with me, but you're disagreeing with the Torah." And if they say, "No, but there are some rabbis that are coming to the event." And you could tell them, "Well, the Torah says it's forbidden both for regular people and for rabbis. And if somebody is going there, obviously they're violating the Torah regardless of what whether they are a rabbi or not, because even Korach was a rabbi. And he's in Gehenna until this day." And that way, these people can at the very least have some sense of truth told to them that could potentially change their mind. I mean, not change their mind, but it's certainly going to affect their neshama in one way or another. But, if you don't care about them and you just prefer for them to burn in Gehenna, then by all means, don't tell them.
