That's a line from a dystopia tv series about a virus that's killing off humanity. One person is infected in a highly unusual way. He is healthy but for him the virus is like something out of a superhero movie. He's a sort of human bioweapon and the virus has a level of mind control. He had been fighting to save people but because his mind has become more and more poisoned over time - he has that new philosophy. And - of course - it's the way covid ghouls think about covid.
Huge spoiler
I'm watching a dubbed version but I assume that line of dialog is the same in the original. The series is in Danish and that season was first broadcast in August, 2020.
I've given a huge spoiler and I think the series is serviceable at best but if you're still interested...
The Rain (TV Series 2018-2020)
After a brutal virus wipes out most of the population, two young siblings embark on a perilous search for safety.
Indeed, it didn't help that I watched Dark around the same time and vibed much more heavily with that though.
