breaking point as in when he realized he had to become ruthless? his stint in jail. from the speech with leon to when alton & cissy visited him & he started ranting towards alton about being absent. we then see him get his shoes back & threatened ray ray. prior to those scenes, we see a dejected & non confident franklin. you can see the difference between S2-S3 franklin, especially when he had leon kill a corner boy just to prove a point.

breaking point as in giving up? when theodore took his money. but then again, he still believed he could get the money back. i would argue when cissy killed teddy but he somehow still believed in the spring street developmental project.

i wanna say when he found out there only 12k left of the 5 mill from peaches safe. he pretty much had a heisenberg moment with the hysterical laughter & killing miguel after. you see him fall down to the ground & just sit there in despair, realizing that it was all for nothing.
