Devil tattoos are usually dark and evil tattoos that people love to get as creative with as they can. The person can do almost anything with their design, letting out any kind of evil look they desire. Most devil tattoo designs are incorporated with an angel design. People incorporate the angel and devil together because of the fight against good and evil, light and dark, pure and sinful. These designs are mostly tainted towards the evil side.
Many tattoo artists are designing angel tattoos that can resemble both good and bad, depending on the person's personal conviction and style. By doing a little search on angel tattoos you could find many devil designs mixed in the results. The reason is because in today's world there is not a fine line of angel and devil tattoos. The good and bad between the two designs is whatever the person wishes it to be. This is not to say that all angel tattoos are leaning towards the devilish side, as there are many angel tattoos that depict what you might see in a book about angels, beings of light and fighting for good.
