Brendan Gregg’s Brilliant Jerks in En­gi­neer­ing is an excellent discussion of the "No Asshole Rule" applied to software engineers.

He posits two kinds of brilliant jerks, the selfless and the selfish. You might call them unempathic and so­cio­path­ic, re­spec­tive­ly. The former, if they develop some emotional in­tel­li­gence, are worth saving. The latter are simply toxic and probably need to be fired.
