It’s from the Onion! The artist is Ward Sutton but he’s drawing the comics from the point of view of a character named “Kelly” who is a parody of an old right wing guy (according to the Internet) who hates political correctness, hence the exaggerated scenarios in the comics. The “haha yes” sickos guy (who I guess sometimes shows up in a thought bubble) usually feels like a parody of how the right views various left wing policies in that the comic overplays / exaggerates the disastrous effects of said policies (to make fun of how absurd those fears are) while the “leftist sickos” cheer on the disastrous results.

The comics basically make fun of how extremely the right views progressive policy and the sickos guy is kind of pointing out how absurd it is to view someone as bad faith (ie a sicko knowingly cheering on the disastrous effects of a progressive policy) who supports something as simple as green energy, drug legalization, or bike lanes. It’s fun to use as a reaction image to anything progressive happening because obviously wanting something like for example affordable healthcare obviously doesn’t make you a sicko. (Or in this case wanting a terrible person to actually face actual legal consequences for the harm they’ve done)
