YMMV / The Shaolin Temple (1976)

• Complete Monster: Master Monk Hui-xian and Ma Fu-yi, introduced as a particularly nasty senior monk and an arrogant kung-fu student, turn out to be traitors working for the Manchurian court. Working in tandem to overthrow the Shaolin Temple, the traitors attempt killing the heroes in sparring accidents before sabotaging their training with near-lethal results. Arranging for an invasion, Hui-xian and Ma Fu-yi stealthily kill the resistance forces guarding the temple gates before allowing the Manchurian army to enter, with Hui-xian poisoning the senior monks and the two overseeing the temple's takeover, with hundreds of monks, trainees, and resistance members alike killed in the subsequent massacre, even helping the Manchurian army in hunting down their former friends.
