Dio is currently very unhappy with this individual. The self-styled detective appears familiar with international customs in a way that chafes at Dio, whose own travels have inculcated far less information into him. On a more serious note, Akechi preaches the virtues of sharing personal information and taking solidarity in less murderous "well-known acquaintances". Even if Dio did not have robust rhetorical objections to this mindset, he happens to have strong personal reasons for not being forthcoming, and he is in a weak position with no preexisting friendships and little interest in forming new ones, so he attempts to tear down Akechi's higher status.
From the word go, Akechi rubbed Dio the wrong way. He was nosing around for information that Dio wouldn't want to divulge under the best of circumstances, and once Dio set his heart on activating Rule Seven, Akechi the busybody was actively detrimental. Akechi also made a show of his cosmopolitan qualities. This really irked Dio who had never travele the world, eaten nice food, or studied the arts. He perceived Akechi as exactly the sort of spoiled little police brat who would have been bribed to exonerate the murderer of his ancestor Left. Dio has been thoroughly indoctrinated to consider these people as corrupted puppets instead of trustworthy righters of wrongs in mainstream society.
Dio was distressed when Akechi condemned him but mostly because his own life was in danger. Akechi had never been an ally and wasn't betraying him, per se. When Dio recognized there was no digging himself out of this hole, he took a petty delight in dragging Akechi down with him as much as possible. Akechi was the symbol of what Dio really thought was killing him: A filthy world Dio had to risk his life fighting. He even speculated Akechi was just sucking up to cover his tracks for a future crime of his own.
The trial and execution of Goro Akechi changed Dio's life forever. For the first time Dio fully experienced the pain of his unfair circumstances. He heard that young men taking murder orders from old men were abuse suriors, and instructions to trust no outsiders were a manipulation tactic. But these sweet words weren't directed at Dio. No, they were talking to Akechi. The detective who told Dio that his mission in life was bringing harmers of innocents to justice, Dio's mission be damned? No, he murdered two completely innocent people because the only innocents he actually cared about avenging were himself and his mother, and he was going to achieve this goal somehow by murdering people to benefit his Japan-governing biological father!
Dio had been raised for murder-suicide missions his entire life. When he came into contact with a corrupted woman, he survived harsh punishment. That Akechi would not accept the risk of death for stoppng Shido's ongoing crimes, that he wanted to live to see the look on Shido's face, that he thought protecting his beloved Akira outweighed his principles of not killing innocent people—Dio saw greed that went far beyond his own execution of orders.
And everyone loved him. Akechi in his last minutes thought he had more dignity than Dio. Three people risked their whole-ass lives for him. The only person with serious concerns was slapped. Dio learned that love really existed, but it wasn't for him. Wanting love was unreasonable and painful, so Dio channeled his negative emotions into his preexisting dislike of his adversaries. And in the graveyard the only adversary available on such short notice was Akechi himself.
Underneath all his pettiness and immaturity Dio is an adult. He can sometimes follow the principles of not making things awkward. When he first saw Akechi again he made a cold but sincere inquiry into tactics. When Akechi revealed his notions of giving up, Dio really lost it—even now Akechi was not conducting himself in a heroic manner and yet acted like he had a leg to stand on next to Dio. This was the best Dio could do at trying to make peace, and he sank back into potshots at Akechi's hypocrisy instead of getting vulnerable with his true grievances. Good or evil, Dio wrote off Akechi as an unlikeable snob. And yet without comparing himself to Akechi, his master to Shido, he never would have become the good person he is today.
