These are all the endings to Cry of Fear from worst to best (not including the secret ending).
Ending 1 - Arguably the worst ending, with Simon killing himself and murdering Sophie and Doctor Purnell, as well as developing a deep hatred for the world.
Ending 2 and Ending 3 - Simon commits suicide and murders either Sophie or Docter Purnell, but acknowledges the person he spared for their help.
Bad Survival Mode Ending - Simon commits suicide, but doesn't murder anyone.
Doctor Mode Ending - Simon is saved from commiting suicide since Book Simon can't kill him due to him being dead although Simon is still depressed and his state is still existant.
Ending Four- Simon overcomes his evil self and doesn't kill himself, but accidently kills two cops in the midst of his psychosis.
Good Survival Mode Ending - Similar to Ending Four, but Simon doesn't kill the Cops.
Co-op Ending - Simon isn't crippled and begins a relationship with Sophie.
