The Russians were pulling out of the Continental System (embargoing the UK). If Napoleon let Tsar Alexander do this without consequences, it would break apart the order Napoleon had sought to create in continental Europe. Most nations in Europe at the time hated this system because it hurt their economies, and made them effectively subservient to France. You can imagine how one nation breaking away from this system unpunished could trigger a cascade of rebellions.
Napoleon actually successfully invaded Russia, and he took the seasons into account. What he didn’t count on was the Russians deliberately going scorched earth on their own territory and even setting fire to their own capital.
For several days Napoleon sought to parlay with Tsar Alexander after capturing Moscow, hoping to reach a settlement. The Russians wisely kept him and his army waiting until they were forced to begin retreating due to a lack of supplies.
