The fundamental reason for a tattoo is often related to the remembrance of a loved one. We are cautioned not to mark our bodies to remember the dead. So the idea has been around for a long time. Not passing judgement, just making the reference to historical practice.
Leviticus 19:28
King James Version
28 Ye shall not make any cuttings in your flesh for the dead, nor print any marks upon you: I am the Lord.
