Which direction of slightly tilting the Earth will be most destructive?

I am a vengeful scientist who crash-landed on your Earth. While I was repairing my space ship, I had to obtain nourishment by consuming organic matter, and visited a local nutrition warehouse your people call "Arby's."

I have decided that the species responsible for this perversion must perish.

Fortunately, I had a spare Axial-Tilt-Tweaker-9000 aboard my vessel. I understand that your Earth has a delicate climate that can be easily affected by tilting the planet. While I have no doubt that the device will be soon discovered and disabled by your species' caste of handsome action heroes, it should be able to alter the axial tilt of Earth by several degrees over the course of some years or decades but will stop well short of turning the Earth on its side.

How much change to the Earth's tilt, between its rotational axis and its solar orbit, would be enough to cause unimaginable disaster and suffering on this planet, and should the axial tilt be increased or decreased?

Edited to add: This would take many years to affect the planet.
