But the last scene with misato and shinji wasn't about her being starved for attention. It was clearly an attempt to motivate shinji in overcoming his sense of hopelessness and fatalism. It was still fucked up but her putting moves on Kenji wasn't related to her need for attention. She was also trying to mask the severity of her wound. Shinji didn't need the additional stress of knowing she was on death's door while he was trying to "save the world." He needed motivation that something in his life would be waiting for him after he succeeded.
