Everyone who does wrong hates the light and keeps away from the light, afraid that his deeds will be exposed.
In context
18Whoever believes in him is not judged; whoever does not believe stands judged already, for not believing in the name of the only Son of God. 19And the judgment is this: the light has come into the world, and people loved the darkness more than the light, because their deeds were evil. 20Everyone who does wrong hates the light and keeps away from the light, afraid that his deeds will be exposed. 21But whoever lives by the truth comes to the light, so that it may be seen that his deeds have been done in God.” 22After this, Jesus went with his disciples into the Judean countryside; he stayed there with them and baptized.
