The bad end goes as follow:

Spoiler for Bad end, chapter 5:

The game gives you a choice when Kyouko claims she couldn't get in her room because Byakuya still has her room key. From there, if you choose to expose her lie, she cannot go on any longer.
She is then executed in the same fashion, and after her death, the remaining survivors "live" in the academy. We see a picture with Byakya holding a picture of Touko in black and white (huge implication she died somehow), while Aoi is taking care of... Makoto, Yasuhiro and Byakuya's kids (a direct reference to a joke where Yasuhiro predicted that both Makoto and his kids would have the same mother, much to Makoto's horror).

However, this is of course a random "dream" Makoto had, and the game immediately throw you back to the choice after this sequence, with Byakuya asking him to stop spacing out right in the trial.
