This is all part of dating. You are going to hurt some people along the way. It would be more hurtful to him if you were to not tell him the truth - you do not love him. He will find out one way or another that you don't have feelings for him. It is best to tell him as early as you can. If you wait any longer, he will be even more hurt.
I will do my best to reply with an educated, humble and honest answer. Ultimately, it is up to you whether you want to listen to my advice or ignore it completely. Sometimes, my advice may be wrong; occasionally, it will be right. Regardless, I want to do my best to give people answers they are seeking.
