If you were a vampire, what or who would be the type of people you'd go after to kill and eat?

How considerate!

According to legend, people who are terminally ill would give you their diseases and their blood would taste bad. Homeless people are people too. I would likely die of starvation as being a vampire would not be desirable for me.

The slow ones

I'd feed on the people I don't like

Pedophiles, murderers, any man that commits violent crimes against other people especially those against women and children.

New answer: I would slowly build up a portfolio of investments to live off of while preying upon the homeless, and thanks to Deadcutie's suggestion, young girls who get baited into a vampire club. Once the investments begin returning substantial revenue I would purchase a large, remote tract of land and begin building a human farm with tools to take just a little bit of blood from many livestock humans at once that way they don't just die and offer perpetual sustenance.

Rapists, serial killers, human traffickers, pedos...pretty much any one that preys on vulnerable people...will become vulnerable to me.

Assuming a sense of morality is at all retained? Probably the homeless as they'd raise the least alarm when they go missing.

Young girls.. easy pickings , and I'd keep a few as slaves

Mean people. F them!
