This is a very wrong notion
Had that been the case then Duryodhan was not stupid to have not understood by the time of the war that he was no match for Arjun, he would have side tracked Karna then but he didn't.
When he became the Yuvaraj, Pandavas were thought that be dead, Karna was no longer needed to counter Arjun now, Karna should have lost his significance if he was only a weapon/counter to Arjun, but he remained Duryodhan's closest friend
And finally during Bheeshm Parva, Karna rejected to fight under Bheeshm, forget someone using, even unconditional friends would have issues with a bff who after having pestered and constantly provoking one for the war, suddenly back out at the last moment. But Dury respected his decision and agreed for it
Nothing shows that there was any selfishness in his friendship and there are multiple proofs otherwise
Just because Duryodhan was a villian doesn't mean he can't have one good quality. He was a good friend not only to Karna but also to Shusharma, else the latter wouldn't have been ready to sacrifice his life for Dury's sake
