When in the face of evil you do nothing you give room for the growth of evil. Evil can't grow and spread if good people are standing in the way.

Evil unchecked will have terrible consequences but Good in the place of evil will also have enormous results.

There are many different ways to accomplish good:

Donate Food to those in need

Donate time to help others

Donate your time to teach others skills

Be kind and thoughtful to others

Smile and be friendly

Care about what happens to others
