How much pain can atheists withstand ?

[Astreja]

My definition of evil:  Deliberately causing pain and suffering to a sentient being.

I would amend that slightly to, ‘Deliberately causing needless pain and suffering to a sentient being.’ For example, jabbing a child with a sharp metal object is evil if it’s done for shits and giggles. Jabbing that same child with a sharp metal object in the process of administering a tetanus vaccine, not so much.

Good point; I concur that sometimes pain is unavoidable when trying to help someone.

Causing pain for shits and giggles is definitely the style of the Biblical god, though.
