Lee (optionally) murders people who attack the group or are threatening him (and probably Clem). He doesn't seem that dangerous to the group.
Ben isn't a murderer but he gets people killed. So he's more or less one. If Ben feels in danger or is outsmarted, he's dangerous. And since he's not very smart and there's always danger, he's pretty high risk. There's nothing you can do to mitigate what makes him dangerous.
Lilly didn't murder in cold blood. She snapped and murdered someone in hot blood. However, remember she rounded people up because she was flushing out the traitor. Traitors make her paranoid and unstable. It's unclear if she now sees traitor everywhere and is dangerous no matter what, or if the problem was the traitor provoking her. If you're not a traitor or defending one, Lilly doesn't murder you. It seemed possible to keep her homicides under control, at least before she snapped.
Kenny is also paranoid (he suspected the barn, where he turned out to be right), but he doesn't murder people because of it. He murders people who might not be dead. He'd maybe murder someone who is knocked unconscious without checking for a pulse. He abandons people he thinks are lost causes (see the girl being chased by zombies), and depending on your playthrough, he will instigate dangerous situations and then not help (see the barn). He's dangerous, because you can't prevent getting into dangerous situations or becoming wounded or temporarily incapacitated. You can mitigate one of Kenny's dangers by not following his lead into a fight or expecting him to back you up.
So, it's a question of whether you think that you can handle the homicidal triggers these people have. By the end of episode 3, Lee is the safest murderer to have all along, and the others all seem pretty dangerous.
Just because Ben made a mistake (he thought he was protecting his friend) does not make him a murderer. And not helping others does not make him dangerous, it makes him useless.
And it doesn't matter if she was "flushing" out traitors (this was Lilly shouting at people she didn't like and making wild accusations) she still shot an innocent with no proof. If she can do that to a person as likeable as Carely, there's no reason she can't one day start suspecting Lee and talking crap about him. She was clearly unstable and so a threat to everyone, an ACTUAL threat unlike Ben who might just leave you to die.
And Kenny murdered a man who may have been dead and may have about to reanimate and kill everyone in the meat locker, which would lead to Duck and Kat getting eaten and Ben and Carely possibly getting ambushed. It's not hard to see why Kenny made his choice in the meatlocker. Also he left a person who was already bitten and basically dead, so others can survive. And he saved your life in ep 1. And in ep 3 if you make the right call.
Say what you want about Ben or Kenny, the worst they will do is leave you to die. Lilly was a real threat and a loose cannon. As far as risks go, it seems to be
1. Lilly- Shot and killed an innocent with no evidence
2. Ben- Made a mistake with the bandits and might leave you/Clem in ep 4 (Its not set in stone)
3. Kenny- Doesn't help Lee's who made the wrong choice in the meat locker escape immediately.
