I might have put too much effort into this one. Might have.
I think the main reason Redd hates Edd so much is because not only did he try to kill him, but he also killed his friends.(Redd’s original Matt Tom and Tord, who will remain dead.)

Tom: “Huh? What is that supposed to mean…”

Tom: “…What?! They only left to go to the store!”

Tom: “There’s no way they could’ve … they’re … they’re fine, they have to be…”

Tom: “…And now you’re telling me Tord is alive?!”

Tom: “What is this, some kind of sick prank?! I don’t have to deal with this–”

Tom: “…”

Tom: “M-maybe I should call them … just in case…”

Tom: “Hello? Edd?”

Edd: “Hello?”

Tom: “Oh, thank god. Everyone’s saying that you and Matt are dead, I know it’s stupid but I just got worried and–”

Edd: “…”

Tom: “…Edd…?”

Edd: “Haha, got you! I can’t answer the phone right now, so leave a message after the beep! Beep!”

Tom: “…It was his voicemail…  That asshole…”

Tom: “I’ll try Matt, he always has his phone…”

Tom: “Hello? Matt?”

“We’re sorry, the number you’re trying to reach is currently unavailable. Please leave a message at the tone.”

Tom: “…..”

Tom: “Now I’m getting really worried…”

Okay, if we didn’t already know that Sam Pepper was the dick cheese of society his new video is literally of him kidnapping two viners, one of whom was in on the joke, and tying them up, the pretending to KILL one of them as the other one SOBS HYSTERICALLY
I literally cannot conceive how fucked up you would have to be to go through with something this sick but the video is painful to watch
My favorite part of this oh so funny joke is when the guy screams “no! He’s all I have!” Real funny Sam. Hilarious
You sick fucking bastard.
