In Islam, we already have a category for acts that are not recommended. Those fall under the category of makrooh or disliked, such as having bad breath while going to the mosque or the category of masbooh, which means permissible, but neither recommended nor disliked, such as driving a car. Tattoos are not makrooh, but straight out haraam. The hadeeth in Bukhari cannot be any clearer. The Prophet PBUH did not curse things that were merely disliked.
For example, the Qur'an merely prohibits the consumption of alcohol, but the ahadeeth expand this prohibition to its buying, selling, production, etc. Does that make those actions merely "disliked"?
Only the Shi'as and their ayatollahs claim that any kind of tattoo is permissible, but then again, they reject the saheehayn.
