A second workout would be contraproductive. Keep in mind that your muscles don’t grow in the gym, they grow when they're resting
Another question:
When lifting whether it's arms, back, chest, or legs I tend to do as much as possible. Obviously within my limits. I basically go to the point of muscle fatigue to where I cannot do a rep even with lower weight.
After morning workout I'm exhausted, I have a great pump.
I go home eat then go to work.
When I get home at night (about 8 hours after morning workout) I have alot of energy and feel as if I can work out the same muscle group again.
With that said, should I go back to the gym and do a second work out, or is that too much. I do not want to damage any muscles and or overtrain.
I've heard if you overtrain then it's actually pointless. Your muscle will not recovery as it should.
Thoughts?

Yes, you are over training. Don't workout 2 times in one day unless you are on massive amounts of gear.
Post your workout in detail. Sounds like you probably need to lower the volume and increase intensity.
