He could have just given her a pill and sealed himself up in his cave or just walked away. I get the idea of him trying to avoid any sense of trouble, but it can be taken to an extreme that makes him seem...kind of brainless at times. After all, refusing to help or even dragging the woman around the jungle are actions that can bring about future trouble. I can't imagine she'd be happy about either one. In the name of avoiding trouble, he created the opportunity for future trouble. This is a common issue with a lot of stories with low-key protagonists. They overthink things and take their desire to avoid thd limelight to such an extreme that their behavior eventually leads to the very outcomes they wanted to avoid.
