This product has a defect.

The negative consequences of his actions began to appear.

He is thought to be the embodiment of absolute evil.

His character ended up falling to the dark side.

He used his malicious knowledge to cheat on the test.

That decision had a bad effect on our project.

His room reflects his bad taste.

This test had too many malicious questions, making it difficult to solve.

Due to bad weather, our picnic was cancelled.

We need to break out of this vicious cycle.
