Also they weren't interested in betraying Marley at that point (they probably still aren't), which is essentially what they would be doing by robbing them of their titans.

Also I don't think all the warriors combined stand a chance against the founding titan anyway. Not only can it take a form more massive than even the colossus and wall titans, but with one scream it could turn any nearby eldians into wall titans capable of easily crushing the warriors underfoot. Reiner couldn't even deal with a normal sized pure titan of Falco 1v1 when Zeke used his weak imitation of the founder's abilities to turn him into a small titan under his control.

Not to mention that the founder is also capable of manipulating their memories and bodies at will. Eren undid all the hardening on their bodies, so there's no reason that he couldn't simply do the opposite and force them all to harden into statues. Or even a crystal prison like what happened to Annie and the previous Warhammer Titan. The Warriors knew the effectiveness of the titans were diminishing as weapons of warfare. Once that happened, the world would have no reason not to kill their own eldians as well. If they manage to achieve their goal, to retrieve the Founding Titan from Eren, the world would no longer have to fear the Rumbling and would be able to safely exterminate all eldians in Paradis using their airforce, and as soon as they did they would also have no more need for their own eldians. One way or another, they were doomed.

Reiner knew the truth, that the people in Paradis aren't devils. With the above arguments, I think Zeke would have been able to convince him, and with his help convince Pieck and Porco. In the end, I think it was their best chance, for them and their families, to live the rest of their lives in relative peace.

At the time, Eren could only transform into his "Normal" Titan, he didn't even have the Warhammer yet. As far as Zeke knew, taking a lonely Eren down wouldn't be a problem. Of course, we now know that, if Eren made a deal with Ymir then, Liberio would be @#$%, but Zeke would never have imagined that could happen.

Supposing Eren had already earned Zeke's trust then, I'm still trying to figure out exactly what Zeke meant when he said "If we were to touch now it would be bad..."
