You were asking why people want him to jump. The answer is simple, they just want to see show and entertainment. No mater which price somebody need to pay.... That's how sociaty is today...
Yay! My favourite Rammstein song. Such a shame they don't do it live because it's a proper banger and they could do a cool visual effect with the ending. But yeah, society just wants to see someone fall.. he is their entertainment
It pretty much says in the song why they want him to jump. They say 'redeem/release me'. Yes they want entertainment but there's also a sense of 'jump so I don't have to'.
It is plain simple. Cruelty, thirst for entertainment. Humans are the only species killing for pleasure and enjoying seeing gore. The guy wanted to have a nice look from the bridge but the people thought he was going to jump. Then they insisted that he jumps because they did not want to get disappointed of missing the show. It is like that from the gladiator times. Just human nature. Creepy song.
