Napoleon when he returned to power

I understand if this is deleted since it’s not directly related to WWII. For those in France I have a question regarding Napoleon and his return to power after his exile. From what I understand he was welcomed by the people in Paris and possible other French peoples when he returned from exile and Louis XVIII fled. My question is this. Did the people of France view the coalition against Napoleon as help or interference? I’m from America so much of World history is only partially taught. IF Napoleon had been allowed to remain in power after his return, how different would world history have been? Did the common French person like him and/or his policies?
