Dragon Ball Z, Season 6

Android 16:
Gohan... let it go. It is not a sin to fight for the right cause. There are those who words alone will not reach. Cell is such a being. I know how you feel, Gohan. You are gentle, you do not like to hurt. I know because I too have learned these feelings, but it is because you cherish life that you must protect it...

Cell:
Uh. This sentimental downpour is killing me. It's so nice of you to help, 16. But I plan on doing this my way.

Android 16:
Please, drop your restraints. Protect the life I loved. You have the strength. My scanner sensed it. Just.... let it go... (Cell stomps his foot down on what remained of Android 16's head, killing him)

Cell:
Yet another fighter...you could have saved.

Gohan:
16, you loved life. You gave everything up to save it. And you were just an Android. I let you die...I can't do that...I won't watch anymore. I...I feel it slipping. And I won't watch this anymore! (Gohan erupts with rage)

Cell:
You are making the same mistake Trunks did, boy. Don't think you can beat me just by powering up.
