so my brother got his bass cracked in a show. I was going to ask if this has to be repaired? like what would happen over time? Thank you guys in advance. Also if it needs to be fixed how would we go about it? thank you again. I will post more pictures
Yeah that needs repairing. If left on its own, the crack may worsen and continue to propagate. It's really best to just repair it now.

Fix should be very simple; just inject a bit of titebond into the crack with a needled syringe and clamp it.

Well, technically it could be done, but only in the same way that you could change a cat into a hamburger. It's an unpleasant process, and nobody is happy with the result.
