77% of Republicans believe it's unacceptable to feel joy at the death of someone they oppose, while only 38% of Democrats share this view.

I looked through the provided sources to find direct evidence for the claim about the percentages of Republicans and Democrats who find it unacceptable to feel joy at an opponent's death. None of the sources explicitly report these exact figures or address this precise question. Several Pew Research Center polls and other surveys discuss partisan attitudes, negative feelings toward opposing parties, and perceptions of political opponents as 'evil' or threatening, but they do not quantify views on feeling joy at death specifically.

Because this is a very specific emotional and moral judgment, it would require a targeted poll question to verify, which is not present in these sources.

Therefore, while the broader context shows strong partisan animosity and negative feelings, the exact percentages cited remain unverified based on the current evidence.
