It is brave to be involved
To be not fearful to be unresolved.

Bravery for the sake of bravery is just as negative as acting arbitrarily for the sake of acting arbitrarily.They are both extravagances, nothing more.

Notes: After Eggsy steps on a landmine, Merlin pushes him off and takes the blast himself to distract the guards. As they come closer, he sings this song and steps off the podium, causing it to blow up killing himself and the guards.

I'm never afraid. But in my case it's nothing to be proud of.
