No one likes suffering, and generally, we try to avoid it. However, some suffering is unavoidable, as there are people and circumstances beyond our ability to influence. This is part of the human experience. But we are not neutral, and though suffering is inevitable, how we handle it is optional. If we greatly fear suffering, then we may be tempted to avoid it at all costs, and the weakening instinct of self-preservation might handicap us from maturing in life. God wants us to grow up and become mature Christians (1 Cor 14:20; Eph 4:11-14), and suffering is sometimes the vehicle He uses to help get us there.
