May I ask what’s wrong with being happy when those people die from AIDS?

( I even think I saw Reb Avigdor Miller say that, but I’m not positive)
See The Path of Life: The Shabbos Drashos of Rabbi Avigdor Miller, pages 106, 140, and 168.
I'm not sure I was clear there.
My response was not intended to source an answer for what's wrong with that (as would be realized when
looking it up). I omitted the middle line of the quote because I thought it was just slightly different from
what Rav Miller said (at least in this source), not realizing that made it look (without reading the quoted
post in full) like this was about whether Rav Miller had said "What's wrong with...," which it wasn't.
