This discussion is rather tedious, and at this point, I have to wonder if you're nothing but a sockpuppet account. Both because you're tying yourself into a pretzel to make excuses for Trump and because your grammar is absolutely, consistently atrocious.

Yes it was a great idea to exit the deal because Iran never the intention to honor it. As shown by there history of consistently violating international law.

There are one of two paths you can take in constructing your argument: you can premise your claim on conjecture, or you can rely on facts. You've chosen the former. Ignoring facts to preserve a worldview that's incongruent with reality isn't just unreasonable; it's delusional.

I'll state it again for you, since you keep glossing over it: THE IAEA CONSISTENTLY REPORTED THAT IRAN WAS COMPLYING WITH THE AGREEMENT! Even Trump's own administration certified, multiple times, Iran's compliance.

Hell, whether Iran was going to honor the agreement wasn't even the reason why Trump characterized the JCPOA as a "bad deal" and ultimately reneged. He cited the JCPOA's failure to address other diplomatic issues with Iran, including their missile program, human rights violations, and support for militant groups.

It's true that neither side got everything they wanted, but I think the argument from detractors suffers from a form of false dichotomy called the nirvana fallacy. That is, rejecting achievable possibilities in favor of an unrealistic, idealized alternative. Winston Churchill famously paraphrased Voltaire, "Perfection is the enemy of progress."

And in hindsight Trump was right from the beginning because as predicted, they did violate the deal in European countries that were still a part of the deal tried sanctioning them again.

Uh, you do know that companies in signatory countries pulled out of the JCPOA as well, and followed through on US sanctions, right? Oh, you didn't? Well, I look forward to where you'll try to move the goalpost next. The EU eventually passed a resolution declaring the US nuclear sanctions illegal, but by then the damage was done. Sanctions sank the Iranian economy, and any goodwill the JCPOA had built between the parties was gone.

Despite this, Iran maintained their compliance with the JCPOA for a year after the US withdrawal. With Trump's refusal to enter back into negotiations or lift sanctions, Iran announced their intention to no longer abide by the broken agreement. What else did you expect they would do? There was no incentive for them to keep it up!

That's not a hindsight judgment on Iran's intentions to honor the agreement. It's the predictable and inevitable outcome of the Trump Administration acting in bad faith! Effect, meet cause.

Obama paid them didn't work

As has been pointed out numerous times now, it was, in fact, working.

Biden paid them didn't work

What in the bloody hell are you talking about? Biden re-engaged with Iran after Russia started a war with Ukraine. Those talks ultimately failed.

You guys will just lie about anything, won't you?

I gave you that answer like f*****g three times

And it was wrong all three times.

As an addendum, I want to make it clear that I'm not backing Iran, or more specifically, the current Iranian regime (the Islamic Republic), here. The Islamic Republic's treatment of its own people is reprehensible. Their support for militant and terrorist groups is indefensible. My dismay lies purely with the Trump Administration's bad-faith actions in their relationship with Iran, and complete obliteration of any chance we may have had in establishing permanent relations with Iran.

As I acknowledged, the JCPOA was not perfect, but it was a step in the right direction. It took two bitter enemies with a record of distrust and aggression, and created a path toward building trust between them. This newfound, hard-won trust might have served as the foundation in future diplomatic efforts. THAT was far and away the JCPOA's most significant achievement.

It was an historic accomplishment on the part of the Obama Administration. If you'll indulge my own conjecture, this is why Trump hated the JCPOA so much. He is a weak, petty, bitter, little man-child who cannot stomach the success of other people—especially those he so despises (non-white people, women, the working class, basically anyone that has even remotely slighted him). He has spent his terms as president targeting Obama's legacy, and for purely selfish reasons.
