why do tom and tord hate each other?

Well first of all, it's not really "hate". Theyre just not fond of eachother.

In the latest video Tord 投稿されました about Edd's death and why he left Eddsworld on YouTube, he states that shortly after Dudette 次 Door, Edd had some technical issues. So he was using an Internet Café. He left Tom and Tord with eachother for a bit, and they found out that they're not really fond of eachother.

They are good フレンズ I heard… just off screen.
They didn't like eachother very much, because they
called eachother offensive names. Tord called Tom a "Jehovah's witness", and Tom… I forgot what Tom called
Tord…

tom called tord a commie または communist,once, and tord responded によって calling edd a "jahobas witness"
(wich is why tom hates Christmas).
; )

Because Tord knows Tom is better than him. >:3

They don't hate eachother. They basically had the same relationship as they did with everyone else in the show. For instance, when Tom went all IN YOUR FACE TORD, IN YOUR FACE!, he probably would've done that to anyone else. Tord 発言しました himself that Tom had a very little effect on him leaving the show.

Because they're both a ファン of violence but in the end only one gets the best weopon または kills the most enimies

At some point Edd had computer problems and it caused tom and tord alone. After talking they found they don't really like each other too much XD. In the 表示する they call each other names like... Idk I can't remember

Tom called Tord Commie, so Tord called Tom Jehovah's Witness. They're both cunts though.

why do tom and tord hate each other?

They don't hate each other, they're just not friends. In real life they're never seen fighting, probably because it's cut または they just don't fight. In ZantaClawz I, Tord didn't do anything bad to Tom and neither did Tom, or, at least that's what I remember last. But in my mind, they don't hate each other, they're just not friends.
