Tattoos were forbidden yes, probaly because they were pagan.
Tatoos are relatively cheap to get, but very expensive to remove, a laser treatment to remove them costs a couple of thousand of dollars per treatment to remove them. too much for most people anyways.
I'd advice against tattoos, because they honestly don't look good on people. In my eyes(my personal opninion this paragraph is) they stick out like a sore, plus they are usually ugly, no matter how pretty the pic is, it looks ugly put on humans.
Plus it damages the temple of God. God created us as we are. He commanded us not to burn ourselves, scar ourselves, tattoo ourselves, becouse it damages us, and the Holy Temple of God.
