I know this is more or less a Trekkie meme, but to be fair, Wil Wheaton didn't create Wesley Crusher or write his lines, he just had to make due with being Gene Roddenberry's Gary Stu.
“The murdered victims were in a church. If prayers did anything, they'd still be alive, you worthless sack of shit.”
He’s more despicable than the character he played.
Despicable? He broadcast an emotional outburst and apologized for it later. That doesn't make him despicable, only human.
And besides, I think he's right.
And you left out the context[0] - that "someone" Wil was replying to was Paul Ryan. Calling for prayers for the victims of gun violence when you oppose attempts to address that violence in any practical manner is an insult to both the living and the dead. To me, that is despicable.

You and Wheaton.
