WTF: GD & Taeyang Tattoo

I just don't get the obsession on tattoos, especially the big one's....

These were tattooed on Gdragon and Taeyang last March 2012 by 302 ARTWORK Studio.

And I just don't get why GDragon would want to have tats saying 
"Forever Young" and "Mind Control" on his body.

As for Taeyang, he has this new crucifix also on his body,
but I think it's tooooooo big.

Anyway, this maybe called "Freedom of Expression" for them.
But for me, I'll say.... WTF!??!
