my intepretation .... Brad (Marc or Andrew) would give to his love/girlfriend/wife/soulmate ect, his daggers; his weapons, his means/desire to fight. Long relationships have a tedency to grow cold, get real nasty- like when you really know someone well, you have the power to rip them apart... perhaps he's expressing that, in love, you have to "give up your daggers"
and as for "proof that love is death" I always thought about it as, like, when you're in a relationship, you give up a lot of yourself for the other person- sometimes, lost in the blindness of love, not even realizing it. you get married, and you grow old together, less independently...
perhaps he's expressing that if he's going to love someone, he gonna do it the right way- gonna love fully, deeply, with patience and tender care, with alll his bleedin heart. But, of course, that would require taking some focus off of individual dreams, which is in a way a death of self. Especially for guys like them, in a band, chasing a dream, trying to find themselves musically. For example, if the boys god married and had babies, touring and making new music would probably take a back seat to things like, oh you know, changing diapers
