Nice buck. Antlers just grew that way. Though developing antler IS somewhat soft/pliable it won't 'bend' without being irreparably damaged.
Typically injuries to forming antler tines result in that tine being truncated.
Often that portion will be dark colored.
Here is an example of that happening. This buck when in velvet had a G3 that had a piece of that tine (about 3" long) going 90° inward.
Later when all the antler was hard and velvet shed, that piece had fallen off and left the truncated G3.
