Congratulations Near.
You have brought this case to its end. You've got Kira, you've outmanoeuvred him. You have won.
You also didn't recur L's mistake. You survived. One could say that you have deceived death.
You did it...

Do you remember those, whom you had sacrificed to win that game?
L had died before you appeared on a stage. You are not responsible.
Takada had voluntarily signed up for all that mess. She just played her part unsuitably.
Yagami had been Kira. He deserved to die.

And what about Mello, with whom you always competed? He would have died sooner or later, living this way. Besides, he was useful.
It is you, who survived, who won that deadly game. At the end you finally defeated Mello. He would be enraged.

You can't remember his puppet's triumphant smirk.
