The quote from Robert Jordan's "Lord of Chaos" suggests that one should be cautious about whom they support or align with, as loyalty can lead to being overwhelmed by conflicting forces. Cheering for both the bull and the bear symbolizes support for opposing sides, which can result in being caught between extremes, ultimately leading to harm.
This serves as a reminder of the complexities in taking sides in any situation; sometimes, neutrality or indecisiveness can expose one to greater dangers. The quote underscores the importance of making deliberate choices when aligning with certain beliefs or groups, as wavering can lead to detrimental consequences.
