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.
In the new Resident Evil series ep 1, 40 min or so in, a line about the zombies not going away and needing to learn to live with them.
But my favorite, a 2020 movie called Love and Monsters, which is overall not too bad, but at the very end... the protagonist who barely survives and only really thanks to other people (one being a dog) and deus ex machina, gives a speech over the radio encouraging other people to put themselves at risk and work on "getting back to normal". This speech, of course, focusing on only his experience and completely ignoring all the other people who died previously.
