The Legend of the Legendary Heroes

All alpha stigma going berserk die. It has been explained twice. Of course they could always make an exception... but I'm fairly confident Ryner is no exception to the rule.
That implies the people killed when he was in ASmode, are his responsability since he was not berserk at the time, only he wasn't strong enough, or willing strong enough, to control his dark side and prevent it from killing.

I don't consider Ryner as a normal Alpha Stigma holder. There's been too much evidence that suggests otherwise.

There's no mistake, he's really a monster by design. His abilities include mass killing of people through a wide range sort of beam and other hard to describe things that are not accessible to normal humans, killing friends and foes indiscriminately.

Well yeah. The only difference between Ryner and Claugh that sets them apart is that one's got an inner psychopathic personality.

I'm more inclined to believe that Sion had the upper hand in that situation. As I mentioned earlier, I think the reason the monster mentioned the Alpha Stigma is to cause panic and show Ryner how the people of Roland also shun him. What's the point of asking Ryner to shoot magic if he had the power left to simply go and directly escape with Ryner?

He didn't have the power to escape with Ryner, but he did say he had the power of going up to Sion and making short work of him, dealing a fatal blow to the troops' morale, before absorbing more shit and/or leaving.

He definitely favours the option of having Ryner escape with him since finding Ryner was the whole point of this journey thus far anyway, but given the above reasoning, I don't think it's unreasonable to think he could have gotten out of that situation relatively unharmed had Ryner considered otherwise.
