1. Yeah, but you definitely have to do it for a few areas just to get to her which shows the intent up to that point.

2. Less justified and more reasoned to do it in the first place. The game goes out of its way to show you as the bad guy you are if you go down that route and make you feel guilty. And the innocent people thing is what separates Undertale from most other RPGs. Although they ain't 100% innocent as they try to attack you first generally (not without reason) up to a certain point wherein it becomes clearly more you than them.

3. Except with Chara you have to do more than that, the point of her was to show you that there is a consequence. Just as you eventually wrenched control of the timeline from Flowey, so did Chara ruin your chance of ever having a happy ending if you chose genocide.

By messing with the game files (the only way to get rid of her) you are going beyond the game to undo that message, that even as powerful as you or Flowey are there's still something there to punish you and rip that away.
