As lasermike026 already said, the USA is in some respects even worse than Russia or China.
Russia doesn’t use capital punishment (still codified, but indefinitely suspended) while the US kills even mentally disabled persons (John Ferguson). The Right to Life is an essential human right in the UN human rights charta.
The US and Russia are quite similar if you compare them case by case. Both use torture, indefinite detention, secret courts, mass surveillance, have an out of control security apparatus (FSB vs NSA). Russia has and the US (example in this BB post) is on the road to state media. Both employ political trials (Chodorkoswky vs Bradley Manning).
The difference is one of quantity not of quality.
