Contrasts between love of sons

Act 1.1 line 107-123
It's very interesting to see the contrasts between Tamora and Titus in reaction to their sons. In Tamora's place, she begs for her son to be saved due to her love for him. Her son, Chiron even comments on Rome's barbarous traditions. However, Titus kills his son within seconds without any remorse. He won't even (originally) allow his son to be buried with the rest of the family and threatens to kill his other sons! Titus, who supposedly represents Roman pride and strength, ironically comes off as the barbarian. While Tamora, contrasts Titus by acting on love. She isn't seen as barbaric, but civil. This is ironic considering that Tomora is the slave and Titus is the master.
