Stay you're blade from the fleash(bad English) of an innocent.

Of the known Assassins that Desmond Miles relived the lives of, Ratonhnhaké:ton was the only one who was not known to have killed any civilians. Altaïr killed an old man in Solomon's Temple during the search for an Apple of Eden, and Ezio inadvertently killed several civilians in Cappadocia by destroying a large amount of gunpowder.
