It depends who raised the dead. If it was a demon, they'll be evil and sadistic. If it was an angel, they would be gentle and noble. If it was another spirit, they'd probably be mischevious or nasty. Even angels are not clear. Some angels may raise the dead for evil purposes, such as intimidating other angels or other malicious reasons

For a clear reasoning of what happens when the dead are bought back, look at Pet Sematary.

"But she was sad and cold, seperated from him as if by a veil. Even though she had been returned to the mortal world, she did not truly belong there and suffered." - JK Rowling, Deathly Hallows
