Yep. According to the Book of Mormon, Jesus killed tens of thousands in America upon His death because of their wickedness and then spoke from the sky and bragged about it.

It is one of the most disgusting lies about the Savior there is.
Hmph!
This statement is false. The Third Book of Nephi states that the survivors of the destruction were already expressing regret for their wickedness before they heard a voice explaining why the destructions came. The voice did not rejoice or brag about the destruction, but pleaded for the survivors to repent and return to faith in Christ. What is wrong with that?
