@Zenaida Normally I'd agree. Hero in this story has a lot of awareness so far though. A lot of people have died covering the noble's duty. He did not "drag" MC into this, he baited him with the ring. MC voluntarily entered to get that ring, which is different from being forced.
Most likely, the front needs more strength or a lot more people will die, and the hero is acting accordingly.
