Pecado translates to "sin". It is the central theme of this classic song, which describes a love so powerful and overwhelming that it feels forbidden by society.
Caetano Veloso questions if his love is a pecado that will lead to punishment (castigo), but ultimately decides that the feeling is stronger than any rule or fear. The use of this word immediately sets a dramatic and passionate tone, inviting the listener into the story of a forbidden romance.
Caetano Veloso gets straight to the point in "Pecado". The song is about a love so intense that it feels like a sin. The singer doesn't know if this love is forbidden or if it will lead to ruin, asking, "Si me lleva al abismo" (If it takes me to the abyss). But despite all the doubt, one thing is certain: "Sólo sé que es amor" (I only know that it's love).
This feeling is described as a powerful force, an unstoppable "torbellino" (whirlwind) that pulls the singer into the arms of their lover. The central idea is that this love is stronger than anything else. It's more powerful than their own life, their beliefs, and even their fear of God. The singer makes a defiant choice, declaring, "Aunque sea pecado, te quiero" (Even if it's a sin, I love you). They will hold on to this love, no matter who says it's wrong.
