This is Crime House.

All of us are shaped by our beliefs.

When we know what we stand for, it can anchor us, making us braver, stronger, and giving us purpose.

But sometimes belief stops being grounding and starts becoming isolating.

And when that happens, confidence can turn into something else entirely.

recognized the voice behind the chaos,

and Ted's reign of violence came to a shocking end. The human mind is powerful. It shapes how we think, feel, love, and hate.
