Bound, destined, and fated can all mean something is certain to happen. Bound stresses certainty from logic or duty. Destined suggests a life purpose planned by fate, in a formal, positive way. Fated is literary, implying an outcome controlled by an inescapable fate.

这三个词都表示“一定会发生”，但语气不同：bound 强调由逻辑或情境决定的必然性，或表示必须做某事的义务，语气最直接、最口语化；destined 强调仿佛被命运预先安排好的人生使命或结局，语气正式，常用于中性或褒义语境；fated 强调受命运操控、无法逃脱，语气更文学化，常带有悲剧或戏剧性色彩。这里不比较 bound 表示“（被绳索等）绑住”或“开往（某地）”的意思。
