Why was he unworthy?

Tensei Iida seemed like a pretty decent guy and hero.

I think it was about the fact that Stain saw him as a symbol of prestige rather than heroism.

It still seems kind of picky from stain.
I mean he was one of the few heroes we have seem who has used teamwork to this extent.
Though I guess that makes him more akin to a police force officer than a Hero.

Stain is probably just an All Might -fanboy gone bad.

Like, seriously:
>ONLY ALL MIGHT HAS THE RIGHT TO BEAT ME

He still have standards and an ideology.
Though it was all based on all might.
And as much as I love all might he IS dedicated to his role as a hero to an obsesive point.
So maybe Tensei just wasn't try hard enough about being a hero.
I would like to see the moment he faces Stain in illegals though.

He decided that not only Midorya is worth keeping alive, but Todoroki too, so it's not like AM is the only one he respects. I'm guessing he didn't like Tensei, because he had a large office and belongs to a rich family. Also he said to Iida that he intended Tensei to stay alive.

Tensei was weak.

He didn't respect the rules

Cuz Stain a fucking shit. SHIIIIT

Yeah Tensei wasn't particulary strong as an individual, he was more of a strong leader type.
Hey, now that I think about it shouldn't All might be super rich with all of the merchandise to his name?

He donated all his profits.

...

Sasuga Toshinori.

is he actually dead?

Tensei represented the establishment of heroes who do their job for fame and glory. Which is nothing wrong, but it is in Stain's eyes since his paragon of virtue is All Might who was the literal symbol of peace and justice who did it for the people.

Cause Stain has a "Guilty unless proven innocent" kind of justice.
He threatened Iida's life straight of the bat.

He had not entirely malicious ideals but he was still an indiscriminate killer.

Paralyzed from the waist down.

He wasn't necessary. Point is, a lot of heroes that Stain claims are phonies could be deemed worthy if he just gave them a chance. But by default, he judge them as being fakes.

Stain isn't wrong but he's not right either.

It'd be more accurate to say he's both.
He's wrong on everything regarding his methods, but in terms of intent he's right on one thing: the current society propagates a lot of self serving heroes, which opens the way to corruption, see: Endeavor using his hero status to force a woman to marry him and play eugenics.

It hasn't come up outside of Endeavor yet (hell pretty much every named hero so far has had a moment emphasizing they are in fact in it for saving others), but I predict sooner or later, whether through Endeavor or maybe an arc following Stain escaping, we'll see more examples of corruption running deep in the hero industry.

For now it's awkward tho, cause outside of Endeavor (who we don't know if Stain even cared about, he might just have a stern reputation rather than a malicious one), not a single one of Stain's named targets feel justified in the slightest.

Nop.

Looking at these now hits a little harder.

...

Oh he does care for Endeavor.
Or at the very least is one of his targets.

Oh, I must've missed that! Thanks.

...

Np glad it helped.

Oh wow I never noticed Endeavor was straight up willing to attack Stain even if it put Izuku at risk.

Oh yeah he jumped the gun super hard.
Also that makes 2 times stain has saved Izuku.

Stain was never meant to be right. Stain was culling heroes, you have to remember, it wasn't simply a matter of cleaning out guys like Endeavor who leveraged their status, but also getting rid of people who didn't meet his criteria of hero otherwise.

The reason Tensei got Stain'd probably did have to do with him being part of a company that made heroes into a community service. Even though they're by all means selfless people doing good deeds, their existence goes directly against Stain's idea of heroes being inspiring icons, because they effectively make heroes into regular people.
