If you've never met Chara "in the flesh", you can rename them. Once you've met them, you can't rename them. T_T They recognize that that is the point that you fell from grace and wiped out an entire species... and names last forever when you've murdered someone.

I believe that's meant to be a self-actualizing moment for Chara and the player, the point where they realize "wow, that's me." Once you know your true self, you can't escape it.

So is life. :'D
