Two extremely aggressive (guys?) fall into a bloodlust and (a) fight (is?) broken up! Two of the fights (are so?) much that everything gets (maybe 'spirals' instead?) out of control. Sigi pisses (instead of localized British slang use 'ignores'?) the harmonious gaiety of his wife so (maybe 'and'?) that (maybe 'instead'?) he kills his old brutal way (which we know because... ?). (this overview is a mess)
