Is Captain Marvel Tony's killer?

[Ichijinijisanji]

Jesus Slott! Stark is a canon atheist, ain’t no such thing as an atheist believing in a “soul”. And this isn’t Tony’s first time rebooting his mind and brain. This existential crisis is just no.

atheists are only atheists because they see no good evidence for the existence of such things as god or soul

however stark's more "i don't fully understand it" territory, but they definitely do exist in the marvel universe.
