Link to the video:(601) Minecraft strength glitch proof - YouTube

As you can see in this video, when I give the wolf strength 255 and apply health boost 255 to myself, it kills me instantly. However, the iron golem with strength 255 does barely any damage even though in theory, it should also kill me instantly given the amount of damage points this level of strength should add. Nearly all other mobs I've tested except the iron golem allow for the expected amount of damage to occur.
