It seems like Dabi was originally gunning for Endeavor but now is trying to take down the whole Todoroki family. I just can't see how he wouldn't know the kind of repercussions his public address announcement would have on the whole family. It seems like he wants to embarrass, shame, and make the whole family (not just Endeavor) contemptuous in the eyes of society.
I don't think Natsuo routinely ignored Touya. I interpreted that scene in 302 where Touya is talking to Natsuo and Natsuo says "why don't you talk to sis about these things," as a kid who is just tired and wants to sleep but his brother is keeping him awake. Yet Touya is like "are you going to ignore me too?"
If Natsuo routinely ignored Touya then why would Touya go to him in the first place crying about why he existed. And why would the children even bother to invite him to play. And even Fuyumi was concerned about him hurting himself but he just brushed her off.
Once he got older, I think Rei was afraid of Touya to some degree. He had a forceful personality, much like Enji, and this type of personality she seems to easily cower under. After that wild screaming episode where he went after his baby brother it became clear Touya was becoming more and more unhinged and wasn't above hurting (possibly killing) other people including his own siblings. So I think Rei was fearful of Touya and what he could do.
I wish Rei had had a stronger personality but I really don't know what kind of life she lead growing up in a family that was willing to sell her for money. Maybe she lived an abused life even with her own parents and they took any will out of her.
In chapter 290 pg 13, Dabi is talking about how Endeavor is trying to establish himself as a father figure and reestablish familial bonds with his family. But how exactly does he know that this is what Endeavor has been trying to do?
Dabi doesn't live with the family to see how Endeavor has been behaving at home and Shoto training with Endeavor wouldn't necessarily mean Endeavor is trying to change if Shoto is just a puppet/doll behaving at Endeavor's behest as Dabi believes. Additionally, Dabi wasn't at the Ending attack to see Endeavor hug Natsuo or hear what he said to Natsuo . . . so how does he know about this change of heart Endeavor has been displaying towards his family?
I guess he spied on them. Rember that Dabi was always gone or came later when the villains did their stuff? He said he tried to find new members but honestly what does he care about the league? I think he was absent because he spied on them or hired other villains to do so. Touya is obsessed with his Dad, I bet he's the stalker kind of guy who spends hours everyday to stay upgraded on his family.
I think what might have helped is if Endeavour had not told Touya he couldn't be a hero. You remember how that crushed Midoriya and his parents (as far as we know) weren't even heroes? For Touya to be the #2's son and not only not be able to surpass All Might, but not even be considered any good as a hero was probably devastating.
Perhaps it was possible for him to still be a hero and use his powers but just not use them at full strength, and perhaps some kind of support item to keep him from hurting himself could have been used.
An interesting back and forth conversation with commentor Shawty has me thinking about something. The villains pretty much count on civilains to quake in fear and not do anything when they attack. And LOV talks about a free society where ppl can do what they want but do they really mean everyone or just the villains?
What if the backlash that results from this upheaval isn't simply a crumbling of the heroes which now allows villains to run free like baby deers in the forest; but now civilians who are on edge are not going to be so docile anymore. They are going to start to fight back - laws be damned. Will this deter the villains who can no longer count on ppl being sheep or will this just cause more and more chaos as various factions go to blows and property is damaged? And what happens to those with weak quirks or no quirks who can't defend themselves? Since they are the low hanging fruit, won't they just be increasingly preyed upon by villains since they are easy targets to hurt.
It's curious, Dabi clearly has a stronger fire power than Endeavor but he has never tried to kill Endeavor himself except that one time when Endeavor was already half dead.
dabi will then immediately die because even he has greater fire power his body cant handle
Also, Endeavor is the #1 hero, and I don't think Dabi is good at fighting physically either, he just burns everything. If it comes down to throwing hands, endeavor wins, easy.
No, I wasn't talking about getting physical. I meant more along the lines of just using his extreme fire power to overwhelm and incinerate Endeavor.
