Help with "To Kill A Mockingbird"

I think Boo Radley is symbol of meaninglessness of prejudices rather than loss of innocence.

the mockingbird also, in a way, represents innocence, kind of the whole they don't do anything but make people happy, innocence, and then the accusation symbolism, that goes with it because these people are innocent of the accusations, and it kinda sorta represents, that these prematurely judged people give the world joy, but in subtle ways, and if you kill their individuality then you are going to be sinning
