Does winning or losing fights via lust to the hostile lizardmen randomly encountered in the swamp affect the chances of getting the Bad/Corrupted ending for the Lizard Tribe?
No, as long as they random you're safe. Only in sparring with lizards of the tribe, pleasuring Rhot and the acolytes when met that rises it. And you have to have 10 lust with both warrior and acolytes to get bad ending.
