Expelled from Quest Help

I'm a neutral Monk who got expelled from quest by leader "You heretic!" I think from failing alignment test which I dont fully understand.

I got the Eye of the Aethiopica and branchported back to the quest level. I can walk next to the quest leader, I read a blessed scroll of taming, then he attacks me and expels me again. The text when I read the scroll is "Nothing interesting happens."

I'm proper level again, am I supposed to do something to fix whatever went wrong with my alignment? I guess I've been eating some meat (chicken enchilada isn't vegan?).

Anyone know what's going wrong or if the game is unwinnable? I'm playing iNetHackv2 which I think is based on 3.6.7
