Bertrand Russell had one very strong reservation against Jesus: he believed in hell. A place where 'sinners' would be condemned to infinite punishment, misery and pain. The concept of such a place educes horror in most people, and certainly the preaching of such a view requires a certain cruelty in character. And besides, this idea goes against the very concept of justice, let alone mercy, of God. A sinner, no matter how wretched, can only commit a finite no of sins in his finite lifespan. And do a finite no of sins deserve an infinite punishment? Most people are really unable to appreciate such obviously inequality of the situation. Perhaps only God with His Infinite Mercy can sentence people to such a dreadful fate.
