You mean Rimuru's thinking or Hajime's? (￣∇￣")
I mean the one who got the title of Hero, he would also be worried for Hajime as well but was rest assured that he haven't gone off of the deep end. If it weren't for the ladies, Yui mostly, he would have turned out worse.
If Rimuru were here, he would be worried about the mental state of the hero. That kind of thinking is toxic.
And also...there is danger afoot within the party
