You are looking at it wrong. The first pic is the south wall which was pushed in. The second pic is the west wall, load bearing wall. The top block didn"t move. The corner cracked open, hinging off the inside of the west wall blocks.
Yes, there has to be at least one or more cracks on the south wall, but not visiable because the basement was finished.
Because the ground is clay, and the dirt is angled away from the house, the only time water gets in the basement is if someone watering her flowers leaves the hose running and forgets.
If the basement was wet all the time, you can rest assured I would dig it out with the backhoe, fix the problem, back fill with sand, put heavy plastic down to act as a roof to deflect water away from house.
I fixed the crack 3 years, so far, no problem.
