Satyamdas said:"I wish I just let her hit me," Fuller told the Daily News on Sunday. "It was out of reflex, just a reaction that went the wrong way,"
"I am very very sorry for the situation she is going through right now, and I am hoping for a speedy recovery"
Doesn't sound like "whatevs" to me. I'm pretty sure the guy realizes she might die. Does he need to get on his knees with tears streaming down his face for you to believe he feels remorse? Or would you take that kind of groveling as insincere or evidence of his guilt. Honestly, the guy probably feels terrible and there is nothing he can say or do that will appease anyone.
Don't apologize enough = OMG you're so casual about this terrible thing
Apologize profusely = See, he knows he's guilty / Thou doth protest too much
He didn't sound sincere in the slightest, I feel judging by what he said and the manner he said it, he just thinks she'll get better eventually. The fact he fled the scene seals the deal, he just doesn't give a shit.
