Random Encounter Kills

• Eddie Low - Murdered by Niko in self-defense (Eddie Low is a random character, so killing him or even encountering him in the first place is optional).
• Clarence Little - Can be spared, although in a later random encounter, he must be killed anyway, unless the encounter is avoided altogether.

Choices

• Jimmy - Niko can kill him during the mission Clean Getaway. It would change the dialogue with Vlad through the phone.
• Ivan Bytchkov - Niko can let him fall from the building, on Vlad's orders, or help him up.
• Cherise Glover - Niko can shoot her in Ruff Rider, or let her live.
• Clarence Little - Niko can kill him, on Francis McReary's orders, or let him live.
• Alonzo - Niko can kill him, or let him warn Teddy.
• Isaac Roth - Niko can kill him in the Majestic Hotel or walk away.
• Vasily - Niko can kill him in a drive-by in the mission Wrong is Right.
• Jim Fitzgerald - Niko can murder him for causing trouble to Ray Boccino or let him ride under train and die in accident.
• Darko Brevic - Niko can either take revenge by shooting him multiple times, or spare him.

Kill One or the Other

• Trey "Playboy X" Stewart or Dwayne Forge - Both characters ask Niko to kill the other.
• Francis McReary or Derrick McReary - Niko can shoot either with his sniper rifle; again, both have asked Niko to kill their opposite number.
• Sergei or James Pegorino-Sergei is killed only in Deal, but, Pegorino is killed in either, but, in deal, he is killed by Dimitri.
