Yes U2 currently sucks. In the past they might not have sucked.

I think there is a difference between sucks and sucked.

It's sad when something that didn't suck now sucks.

If something sucked and still sucks it is neither sad nor tragic.

Brittany Spears sucks and still sucks so to say Brittany Spears sucks is like saying English is a language.

is the future more important than the present? If something sucks now does it suck foreever?

The future is death; the present is life.

I don't care if I suck when I am dead because I am dead.

I just don't want to suck now.
