No, Walt didn't care about anything but his ego. He admits as much in his final conversation with Skylar. The whole point of the character was that he was an incredible egotist who sacrificed everyone around him and hid behind some mantra of 'just doing it for his family'. There are several points in the series where he has a way out, and he chooses not to because he doesn't want anyone else to take over 'his' business. Whenever Jesse starts doing well on his own, Walt drags him back into it; he basically kills Jesse's girlfriend, he poisons Jesse's stepson to force him back into it, and in the end, he doesn't even bother to make sure he is rescuing Jesse, because he is so blinded by his own vengeance. Walt is a horrible human being on every level and never gave a damn about anyone but himself and his incredible self--entitlement.
I hate Walt but even that's sort of unfair. Dude cared about his family, he just cared about his ego more.
this was walt's only redeemable character trait by the end, but even then every villain the show had cared about their families as well. mike, tuco, etc.
I completely disagree; He specifically admits to Skylar that he did it all for his own ego. His behavior shows that he either was unwilling or incapable of caring about his family. He actually knowing associated with groups that were known to kill family members as punishment, even after he had several opportunities to leave. He lied to his family the entire time, up until he got caught, at which point he pressured them into working with him. He manipulated Flynn/Walt Jr in order to pressure Skylar into staying, like he was a game piece. When that didn't work, he threatened Skylar. He got Hank killed because he was an idiot. He even fired a loaded minigun into a room with Jesse, tackling him only as an afterthought. Dude was a straight up monster. This isn't even all the shit he pulled. IIRC, he also killed Mike, manipulated Jesse into killing Gale, got Hank killed, and poisoned a child, all of which benefitted his family in absolutely no way.
I feel like people apologize for a lot of what he did because he had some admittedly badass moments, but even the character admitted it was all a selfish game for him. It's hard to argue otherwise.
