I was talking about the Australian wildfires with a guy from my Yeshivah and he asked me whether there were any yidden affected and he doesn’t care about the goyim. What should I have answered him to stop this terrible idea that we shouldn’t care about goyim at all? After all, Hashem said on the Mitzrim “מעשי ידי טובעין בים ואתם אומרים שירה״. Thank you very much!
It is definitely the correct thing for us to care about all of H-shem’s creations, however this is quite a high level, and not everyone is really holding at that magreida. On the otherhand though, there the source that you are quoting is different than this. The Midrash that you are quoting is referring to singing and dancing that they perished, which is specifically showing outward joy at their demise, that is much worse than this.
