Yes a nice vampire might bite a humans
Vampires generally bite to feed on or to transform humans.
As vampires are entirely fictional they can be mean or nice depending on the author of the story.
Your phrasing is extremely vague. If you want to ask how vampires bite humans, they are thought to have long sharp teeth, which are good at biting.
If a vampires bite a person he or she joins the club and becomes a vampire. This is what is in the stories and movies and not a reality as vampires do not exist
In popular vampire mythology, vampires typically turn humans into vampires by biting them and draining their blood. The vampire's bite infuses the human with their own vampire essence, turning them into a vampire. Additionally, some vampire myths suggest that drinking the blood of a vampire can also transform a human into a vampire.
no, some vampires may think it is wrong.
Although vampires don't exist, I would assume the same way humans do, or, if you follow Twilight, they don't die for the most part, and they could bite a human to create another vampire.
No, a vampire's eyes do not have to be red to bite a human. The color of a vampire's eyes may vary depending on the lore or story, but it is not a requirement for them to feed on humans.
yes vampires do and so do outlaws that get turned into vampires because the vampires bite them.
