No - it's not mean - it's a good question. I think it's a good point that if your friend would have been stoked on something like this, or would have wanted you to get a commemorative tattoo, then maybe it's a good idea. Keep in mind though as others before me have stated that if you do get a memorial tat, you will see it all the time, and it'll remind you that he died, not that he lived. I have nothing but good vibes and respect towards you (and your decision for the tat whatever/where ever you decide) and I know how painful it is to lose a close friend esp when they aren't suffering or sick and it's a random act (one of my best buddies passed away unexpectedly in August '04).
