The research isn't there. Jury is still out on whether the long term consequences are a net benefit. In the end you're talking about increasing emissions for a temporary decrease in temperatures. And the chemicals we have that are good candidates for albedo modification are quite toxic. Today more than 10% of deaths globally can already be attributed to air quality
If India is experiencing large scale mortality from warming, they aren't going to give a damn about your concerns. They're just going to inject aerosols into the stratosphere.
Besides the well-documented increases in PM2.5 concentrations at ground level we already have clear research on we'd also face
- ozone layer depletion
- reduced precipitation in an area already drought-stricken. As well as other difficult to predict effects on local climate and weather
- alteration of many stratospheric chemical cycles. We're talking changes to nitrogen oxide chemistry and even impacts on hydroxyl radicals which drive atmospheric cleansing capacity
- increased risk of acid rain from sulfuric acid
Like I said. The research is not there. There are many many side effects we haven't worked out yet.
And spare me the personal attacks about dishonesty, jackass
Humans tend to not breathe in a lot of stratospheric aerosols, on account of that being pretty high up.
As they sink down, they grow larger (condensation & coagulation). Once they reach the troposphere, they usually get down via precipitation, which also isn't really affecting a lot of breathing.
They can absolutely have other effects (see SO2/acidification, e.g), but air quality isn't really the main concern. For SO2 specifically, there's actually very little mortality sensitivity: https://www.giss.nasa.gov/pubs/abs/wa01010x.html
You're right that the research isn't there yet to make statements with confidence, but that applies to the air quality claim as well.

India especially is experiencing many more deaths from air quality than from warming
