I can't believe people give shit to Soulless Sam for his behavior towards Dean. He never risked Dean life on purpose unless he knew he could pull him through it. Oh no, he let Dean get turned to a vampire? Oh no, he laughed when Meg sat on Dean's lap?
He was just treating Dean the way he's been treated his whole life by his older brother. MINUS the physical and verbal abuse. Dean always talked shit about how unstable Sam is and called him a freak again and again, well. Eat up your slice of humble pie this is how bad Sam can REALLY get.
And to put things in perspective? When other people turned Soulless they killed people in cold blood and turned into straight up criminals. Soulless Sam killed innocent people but never unprompted and without a reason.
Also about the Meg stuff - when you don't have a soul so you can't be traumatized yeah. It's funny to see the demon who sexually abused you straddle your brother making jokes. Like "Wow sexually assaulting me wasn't enough she's going for Dean as well, props for the dedication to the bit".
Sam had his body, mind, and soul violated time and time again by pretty much everyone including Dean so I'm pretty sure that guy doesn't get to complain. Not after the blaming a struggling alcoholic and blood junkie that was violated by a Knight of Hell as an infant and then went on to be abused, manipulated, and controlled by everyone in his life. Tricking Sam into saying Yes to Gadreel after the traumatizing events he went through with Castiel and Lucifer, the sabotaging text about Amelia, blaming Sam for respecting his promise to Dean instead of violating their agreement just because he's so used to never giving a shit about what Sam asked for him - those things are way fucking worse than anything Soulless Sam ever did to him.
And before anyone comes for me, I'm not a Dean hater. I sure sound like one right now because I'm just generally extremely upset about this topic.
