I’ll be a bit blunt, but at what point shall we leave some things to natural selection… Very often, those who set themselves on fire, die very soon after due to infections…
The bigger problem is, in this case, the inability of the system/society to recognise and deal with mental health issues on time or at all… About a quarter of Americans reported Mental health issues… In the EU only about 10% or less in countries with high social awareness…
So, I’d rather ask how to prevent those things happening in the future?
