(Refused)
XXIX
Defendant requests your Honor to charge that the burden is upon the commonwealth to show that the defendant has intelligence and maturity of judgment sufficient to render him capable of harboring a criminal intent.
XXX
Defendant requests your Honor to charge that if no motive has been established for the crime, the jury must regard it as important in its bearing upon the question of the defendant’s mental condition at the time of the commission of the act charged against him.
XXXI
Defendant requests your Honor to charge the jury that if the commonwealth have established merely a slight, trifling, and inconsequential motive for the commission of the act charged in the indictment, they should regard it as important and give it more consideration in connection with the question of the defendant’s mental condition.
XXXII
Defendant requests your Honor to charge the jury that the commission of the crime charged in the indictment by a child of tender years from its very nature raises the question of abnormality of the defendant’s mind and in the absence of clear, strong, and convincing evidence on the part of the commonwealth, it must conclude that the defendant’s mental condition was such that he did not understand the wrongfulness of his act or understand the nature and quality of his act.
