Beskar's claim to be a scanner were absolutely true; he was permitted to scan or vig-kill each night, as you may have guessed... the 1-2-1-2-1 systematic killing just happened randomly and I guess he decided to continue with it.
I didn't always trust in his judgement (I suggested a scan of Joooray rather than vig, for example), but at the end of the day, we had personal goals to pursue as well as a town victory and I fully understand why Beskar did what he did, especially as his own personal goal was the hardest of the Star Wolf members.
