Least trust worthy wrestler ever

[Womb Raider]

The Undertaker - Kane turned heel on Taker multiple times and vice versa from 1998 to 2010.
Mankind - Kane helped Taker beatdown Mankind on the final RAW before Summerslam 98.
X-Pac - In this case, it was X-Pac who turned heel on Kane.
RVD - Kane chokeslammed RVD after he lost the Mask vs. Title match against HHH.
Big Show - I forgot how these two broke up. It was after they lost the Tag titles to Spirit Squad and the team deteriorated.
D Bry - It was a mutual break up, but it eventually culminated in a feud.
Seth Rollins - Rollins helped put further injury to Kane's leg after Brock smashed it with the ring steps.

It seems like The Hurricane was the only one who got away unscathed when it came to alliances with Kane.

Didn’t Hurricane get jumped before their tag titles ladder match? Or was that RVD?

I wasn't really watching RAW as much in 2002-03 and have to go by articles, recaps, and old videos, but this is what the wiki had to say:

"On the September 23 episode of Raw, Kane and The Hurricane won the WWE Tag Team Championship after defeating The Un-Americans (Lance Storm and Christian).[50] The following week on Raw, Kane won the Intercontinental Championship from Chris Jericho, despite interference from Triple H and Ric Flair.[68] On the October 7 episode of Raw, Kane successfully single-handedly defended the World Tag Team Championship in a four-team Tables, Ladders, and Chairs match, as The Hurricane had been attacked earlier that evening by Triple H and Ric Flair and was unable to compete. That match was later nominated as WWE's 2002 "Match of the Year". Kane and The Hurricane lost the World Tag Team Championship to Chris Jericho and Christian the following week on Raw.[69]"

Yep. I was actually rewatching WWE from invasion onwards recently, but I remember that from my childhood.

That was actually a dope time period for Kane.

He didnt join nWo when he heard that nwo was 4-lyfe

I think Nash got injured before there was any payoff to what that was leading to.

 

[Cartier Murphy]

Shawn Michaels because I vividly remember his feuds being over his scumbag behavior, chiefly with John Cena and later as the basis for the Chris Jericho feud in 2008.
He even had a betrayal compilation:

 

[Carl Tethers]

Seth Rollins. He'd turn on you then injure you for real

 

[Breh Obama]

Paul Heyman

 

[Ed MOTHEREFFING G]

If nash stays healthy and hall stays clean, we had a chance for the nWo to finally just be The Kliq in wwe

 

[Breh Obama]

Injury wise…. Samoa Joe

 

[Reality Check]

First thought was Big Show, nikka turned more times than the warm side of the pillow

This. Can't trust someone who has that kind of track record.

 

[Cal Cutta]

Buff Bagwell. It was so obvious he'd fukk over anyone that it became its own comical gimmick.

(if going from the list OP posted, Big Show)

 

[Tanahashi Coates]

 

[TheAlbionist]

80s/90s Jake, but it's you're own damn fault for trusting him in the first place.

Snakes change their skin on the reg.

 

[Killer Instinct]

 

[RiverCity916]

Orton for sure
