`Sea Lion` could become a suicide for Germany since it could give a legal basis for USSR to ally with UK and attack Germany. And again Germany will have 2 fronts to fight.
Second Starting a war with The Soviet Union before deafeating England, or starting that at all, and then switching from Moskow to the Kaukasus.
In fact Hitler and his staff did not have a real choice. After he was in war with UK, he already had a risk for second front in East. Therefore he decided to attack USSR to secure his back and after that invade UK unaware of what could happen behind. UK in 1940/1941 was not capable to attack the Reich with ground forces while USSR was, so in beginning of `Barbarossa` Hitler had no risk to be attacked in back. Risk appeared later, when `Barbarossa` stuck much longer than Hitler could imagine.
What concerns Moscow and Caucasus, this decision was quite logic and correct since in case of successful assault to Caucasus Germans could capture the main oil fields of USSR in Baku and thus leave the USSR without oil. Problem was in lack of resources to fulfill the plan...
