The format of the comic book is allows the authors to weave this tale fluidly through time, space, and tone. I personally enjoy the medium of sequential art, so reading this story was inherently interesting to me. The story left me with many things to think about beyond the striking moral quandary of society versus truth. Here I'll attempt to parse out the answers I've reached to some of my favorite themes.
I was led to question identity when Rorschach's origin was presented. Could one truly be separate from their alter ego? Since heroism is a performative act, without the ability to partition the conscious, then I would argue no. The alter ego is only separate outwardly. To the hero (or villain), they are both, and reconciling those two faces is something that the characters of Watchmen struggle with their whole lives.
