The Tenno are infected with the same Technocyte virus the Infested have, only the Tenno have thus far resisted the mind altering affects of the disease. As per the flavor text for the Ether Swords, it is not unheard of for a Tenno to succumb to the virus at a later stage, and then need to be killed.
