Ironically, Anakin's problem is his love. The Jedi have learned not to make strong emotional attachments with other beings. But since Anakin was older than normal when he started his training as a Jedi, he eventually lets his personal feelings get in the way. Anakin love for his mother led to the murder of the tuskins and I believe that his love for Padme will seal his fate as the Dark Lord of the Sith. Luke had the same problem in the OT, but it worked out for him. And in the end Anakin's love for his son brought about the end of Palpatine and brought balance to the Force. So yeah, its tough to say if love was so bad in the end, but I believe that it was Anakin's weakness, but he redeemed himself before his demise.
