I think primarily incel mindset is about feeling unfair on how you're treated by the opposite gender and this transforming into a rush of hate, revenge and resentment against the opposite gender. Is it like hurt people hurt people?  It would make sense to understand the underlying resentment and why it evolves in the first place. If someone feels sidelined for the longest time in life, I guess at some point the frustration boils over and it's reasonable why this frustration then funnels into extreme resentment. I mean nobody should have to feel a sense of unfairness in life. Everyone deserves love.  I'm not defending incels. Just providing a context and reasoning to why this could happen.
