Nope. The following answer consists of minor-spoilers. Deku became more of a shadow hero than a villain. Actually, he didn't even became villain, his character just went kind of dark.
In the My Hero Academia: World Heroes' Mission movie, Deku is certainly framed as a villain. He's falsely accused of mass murder by Otheon's chief of police and is forced to go into hiding with Rody Soul. By the end of the movie, they both manage to clear their names and remove their villain image.
Villain Deku has many different variations, but the most common is either a cold, calculating villain who uses infiltration and espionage to stay three steps ahead. He hates any hero or is a psychotic outcast. He has completely forsaken the desire of becoming a hero after being turned down by his idol.
Izuku Midoriya has been betrayed by U.A and his classmates besides two. Kyoka Jiro and Katsuki Bakugo.
In order to try to protect people, Izuku left UA and is working with All Might and an elite squadron of heroes as he goes through his Batman phase—better known to fans as Dark Deku.
The reality of the new broken society will transform him into a rogue hero who resembles the symbol of destruction with blood in his hand, wearing a distorted hero costume with a broken smile that was once real.

The "U.A. Traitor" is revealed to be Yuga Aoyama. He was born Quirkless, and with his parents both coming from wealthy backgrounds, they made a deal with All For One to give him his Navel Laser Quirk in a desperate move to grant their son a happy, successful life.

He became a villain by Shiki infusing herself into his body, which makes him a powerful, formidable, manipulative, irredeemable, wicked, insane, heartless, dangerous, murderous, sinister, sadistic, & intelligent villain, also receiving multiple dark magic-related Quirks & his dangerous weapon Giga Battle Nizer.
Instead of being an anti-hero, Deku turns into a villainous Anti-Gods that slaughtered thousands of heroine lives.
It would be a relief to many My Hero Academia fans to learn that Bakugo does not die in the series. Unfortunately, he was severely injured, which is why he has not been seen in a fight in quite some time. It was a blow from Shigaraki that ruptured Bakugo's heart and left him unconscious.
Dr. Kyudai Garaki, also better known by his villainous alias Daruma Ujiko, is a major antagonist in the manga/anime series My Hero Academia.

Academy's walls. In Chapter 335 of the series, All For One alluded to the fact that he was going to activate a traitor within U.A. Academy, with the final page of the chapter seemingly implicating Toru Hagakure. However, by the time 336 rolls around, it's revealed that the traitor is none other than Yuga Aoyama.

As fans saw earlier on in the My Hero Academia story, Izuku Midoriya was able to resist Hitoshi Shinso's Brainwashing Quirk during the U.A. Sports Festival arc.
As soon as she could, Toga bolted to follow Stain, and she went so far as to explain why she took some of Ochaco's blood. It turns out the theft all came down to her unrequited love for Izuku.
Tomura Shigaraki's personality regains control of his body, which means the end of All For One and the rise of My Hero Academia's true final villain.
According to Deku's mother, the inherited quirk Deku should've naturally received would've either been his father's quirk, breathing fire, or her own ability to levitate small objects.
Chizome Akaguro, or better known as Hero Killer: Stain and formerly the vigilante Stendhal, is a major antagonist in the manga/anime franchise My Hero Academia.

Whenever a hero engages in battle, there is the expectation that parts of their costume will get ripped up or destroyed. With his mask being the first piece to suffer this, as it was not well-designed, Deku likely realized there was no point in having it be constantly repaired or remade by the school's Support Course.
How Does Deku Unleash Rage Mode in My Hero Academia? It's been previously teased that Deku's use of One For All would take shape around whatever anger he could have, and fans get to see that go down in Episode 123.
