Would’ve been kinda cool seeing a hashira-turned-demon still supporting the Demon Slayer Corps, tho that’d probably lessen the impact of Nezuko’s story.

He doesn't want demons, he only created more demons because he needed to find the blue spider lily, so he created more so they could find it for him. Muzan isn't the kind of guy who likes to fight, he just wants to be immortal and would do anything for that to be possible.

The biggest mystery is why Kokushibo didn't eat Yoriichi's flesh after the latters death. He was right there, possibly making him sun-immune and much more powerful by eating a strong swordsman.

I just notice that Muzan often turns broken, misunderstood, ill, and traumatized people into demons. He uses that demon person's emotions to prey on humans and for his benefit. I don't think he would turn a pillar into a demon because that pillar might end up being more powerful than he is. A pillar is also something that is supposed to be strong and sturdy. Doesn't Muzan's blood have to be accepted into the the victim? The blood might activate according to the person's heart and emotions.  I don't think the blood can take effect on a pillar as it would a person who has lost hope, has been abused, or just overall had a life that made them feel like humanity failed them. The blood might kill a pillar or a pillar will survive. If a pillar does turn into a demon, they might become more powerful than Muzan. These are just my observation before watching the vid all the way through.

The answer is actually quite simple; he's a coward.
You're right; some demons don't remember their human lives, but if they're strong enough, they do.
And I'm pretty sure Muzan would not want the smoke from a demon powered version of any of these hashira.

It was always weird to me how demons would ask if people wanted to become a demon and not just force them it's not like the majority of them would remember how they became a demon and if they did muzan could easily control them

So I notice that usually the people who had no harmful intentions as humans or were turned against their decision forget their memory. Akaza was turned against his will. He did not remember anything. So was Ume/Daki... She didn't remember anything., but Gyutarou could because he made the decision; which is also why Ume was given the choice to go into the light instead. Rui could barely remember due to conflicting feelings. Gyokko and Hantengu remember due to bad intentions. Nezuko couldn't remember at first because she's good natured, so are most newly demons who eat their families because they don't recognise them. I think that Muzan takes note of this and his blood takes away the good intentioned people's memories in order for them not to rebel and be more "demonic."

5:30-So basically,Tamayo's power can make you see what isn't real while Yushiro's power can make you not see what is real!

About Muzan turning hashiras into demons, I think it is also because if they keep their memories, they may rebel against him and a demon hashira may be a real problem. If we take Kokushibo as a reference, Gyomei  was handling like 75% of Kokushibo by himself, so a Gyomei-level hashira would be incredibly strong, only to be threatened by Muzan, because he can control their cells,
but I think that a demon Gyomei would be in pure strength stronger than Muzan.

I'd like to think Chachamaru was a dying cat Tamayo happened upon and being the caring demonic soul she is took pity on the creature and turned him into a demon. Tamayo doesn't seem like the type of person to go around turning random animals into demons, hence why we only see one demon cat.

Let’s not forget, he only had the upper moons exist so they could hopefully either find the blue spider lily or become immune by chance themselves to the sun.

So you’re telling me the person that muzan in turn into a demon was very important of defeating muzan learn something new every day

Tamayo: i dont need to be stronger than u to kill i just need to make u weaker
Me: wise words wise words

The curse was not saying Muzan , but if they say kibutsuji . They will die , as koku and akaza and other demons said Muzan Sama only so curse was not activated because the curse is saying name kibutsuji

I feel like Muzan could have turned them into demons however it’s not his choice it’s the person who made the show if the decide no then it’s no

Muzan creates demons just for two purposes: 1. Finding Blue Spider Lily 2. Create a demon that can conquer the sun. His main goal is to conquer the sun and that's all.

A better question to ask, why dont muzan kill all of them, its not like he need to hide or anything, the pillars rarely go together, he could make short work of any slayer while being severely weakened, he could probably 1 shot them in his full power

Well kokushibo can be said as the Hashira, tho it never existed during his time, he did get turned into a demon...... soooo you can technically say that he did turn a pillar into a demon

You should make a video about "What if tanjiro met and fought kokushibo"
