Sounds like leader 1 is to blame in that case, not leader 2. Sounds like they weren't secretive enough and didn't take necessary steps for your protection. These days, if I consider joining a clan, I screen the leader as much as they're screening me, maybe more. If they smell of incompetence and / or inexperience, I avoid. (Sorry, noobles).
This is also one of the reasons I don't do life oaths - I will not, ever, let myself be stuck in a clan with a leader I don't OOCly enjoy working for. I want to be able to leave if the leader I trust decides to store.
The same thing can happen if you're unclanned. Templar 1 orders you to do something, templar 2 messes with everything templar 1 is involved in. Killing minions is easier than killing other templars - unless you ALSO talk to templar 2, and convince them of the benefits of your continued existence. Or you're an indie grebber who gets hired for a secret job with Salarr, something that -really- pisses Kurac off. Again, killing the minion is easier than killing the Salarri who hired you.
