Hmm i think he kinda have masochistic instinct! Oh and i think he already like Krieg from the start, remember when they were watching TV and he saw Krieg's smile and he blushed and there was a "badum" moment there! So it's kinda not rape cause i think he wants it to happen too but the wounding him part is not ok!
Yeah, but it is a difference between wanting something at a moment and not wanting it at another moment. The moment someone says No and the partner gets through with it anyway, it is the moment it becomes rape. Your thinking is the along the lines that rapists justify their rape. She/he wanted it. Does not matter if both are in love, if someone says No, it is the moment to stop.
Hmmm... He wanted to put pressure on Krieg's injury but he stopped because he wanted Krieg to heal faster and if he do that it's gonna put more damage on the injury and it could turn to worst!
Krieg isn't in love with him at that time and he did reflected on what he did and try saying sorry on his own way and don't forget the part that he really hated human only Asuka is the exception!
buuut acting all dandy aftery being mauled and raped is a little off-putting to say the least. Like at least get mad at him a little.
