Spoiler:

I'm wondering why Souichirou even felt the need to threaten Mello with the notebook in the first place. He had a gun pointed at the guy, he could have killed him in seconds. In what way is it better to write his name down and watch him die 40 seconds later?

Spoiler for Spoiler:

Mello threatened to blow up the place if they didn't put down their guns. Light then instructs the team to go along with Mello's plan because this will be the chance to see his face. Read the manga, it's a pretty simple explanation.
