Ok, Voldemort was THE DUMBEST DARK LORD EVER. (Yes yes I know this is gonna start a lot of controversy but come at me)
1) What in the name of Merlin was the whole duel thing about in Goblet of Fire in the. Like Voldy, was like "Get up Pottah, I want to duel you!" Like when Harry was just trapped behind that spikey thing holding him back, couldn't have Voldy just been like Avada Kedavra and ~boom~, he dead?
2) Anyone could have just killed Harry by saying "Accio Glasses" I mean, he has pretty bad eyesight, doesn't he?
3) Polyjuice Potion? I mean, Voldy coulda just brewed a little Polyjuice Potion and then sneak into Hogwarts, kill, uh lets say Hermione, grabbed some of her hair, turned into her. Then just kill Harry Potter in his sleep or IDK.
4) Why did Voldemort let pride overcome him when making his horcruxes? Put them in random cans, bottles, clothes and hide them in a sewer or something. Like I get the whole "symbolic objects thing" but lets be honest, it would be way harder to find horcruxes that are soda cans.
5) Okay, more horcruxes. I mean, Voldy has killed a LOT more then 7 people like -_- . He could have easily made a horcrux for every person he kills. It may take effort, but he would go to extreme lengths to stay alive, wouldn't he?
Let me know if you agree, or if some of these could bee disputed because of other things, but I think i got all of 'em. Any other suggestions as tto why he is the Dumbest Dark Lord ever?
He did make some smart decisions thoughh, but most could be better prob.
