So, ignoring the fact that this is bullshit (the new strain of coronavirus has a fairly high fatality rate, but so does the flu; the same populations are vulnerable)...what makes this person thinks that they will beat the odds and not be part of the 50% who die? Or that they could even survive in a world devastated by a disease like that?
If they don't care about dying, then wouldn't the *way* that they died matter at all? Dying from a respiratory infection is horrific. Ditto for dying from any of the things that might kill you if you couldn't survive a post-apocalyptic hellscape. Mad Max is just a movie. It's not gladiators in the fucking Thunderdome that kill you, it's starvation or a lack of medical services.
No one wants to go out like that.
