SB 11.25.11

yada asisa asasya
 mam bhajeta sva-karmabhih
tam rajah-prakrtim vidyat
 himsam asasya tamasam
 
Translation: 
 
When a person worships Me by his prescribed duties with the hope of gaining material benefit, his nature should be understood to be in passion, and one who worships Me with the desire to commit violence against others is in ignorance.
