Oh come on dude! Trust me, rotties are the best breed you would want to have.
ANY dog would bite or scratch if not tamed and trained properly. The temprament of the dog depends on how you handle it. Rotties are one the larger dog breed side and agressive too but can be the best dogs if trained properly.
Rotties killing babies? Every year in India and Pakistan rural areas so many people die due to mongrels biting them..
You cannot have a conclusion about some breed due to some loser briging up a dog in bad shape..
