*Watchmen Spoilers as well in this topic!*
So in Watchmen, Dr. Manhattan is so disillusioned with the very concept of life, and so disconnected with humanity that only after seeing humans as "thermodynamic miracles" does he feel motivated enough to help solve the mystery. Only to become disillusioned once again after Veidt squid-nukes New York. He leaves Earth's galaxy for a "less complicated" one, and suggests that he may even create life.
The ending of Rebirth implies so far that the life he created was the DC Universe.
So the question is, what do you think Dr. Manhattan's role in the DC Universe actually is? And what do you think is motivating him to intervene.
What's kind of confusing is that Dr. Manhattan has always seemed kind of "useless" when it came to his omniscient, time-spanning sight. According to him, everything is pre-ordained and he's powerless to change things, even though he knows what's going to happen. So it seems odd that he'd suddenly play a divine interloper, because he never seemed to move away from that perspective in Watchmen.
Personally, the fact that Manhattan would feel compelled to intervene and influence the DC Universe is what has me interested, which is a shame, because it'll probably be a year or two before we actually see him. But as for now, I was wondering what your theories were?
