“A criminal trial is not a fairy tale wherein one is free to give flight to one's imagination and fantasy. Crime is an event in real life and is the product of interplay between different human emotions. In arriving at a conclusion about the guilt of the accused charged with the commission of a crime, the court has to judge the evidence by the yardstick of probabilities, its intrinsic worth and the animus of witnesses. Every case, in the final analysis, would have to depend upon its own facts. The court must bear in mind that "human nature is too willing, when faced with brutal crimes, to spin stories out of strong suspicions." Though an offence may be gruesome and revolt the human conscience, an accused can be convicted only on legal evidence and not on surmises and conjecture. The law does not permit the court to punish the accused on the basis of a moral conviction or suspicion alone. "The burden of proof in a criminal trial never shifts and it is always the burden of the prosecution to prove its case beyond reasonable doubt on the basis of acceptable evidence." In fact, it is a settled principle of criminal jurisprudence that the more serious the offence, the stricter the degree of proof required, since a higher degree of assurance is required to convict the accused. The fact that the offence was committed in a very cruel and revolting manner may in itself be a reason for scrutinizing the evidence more closely, lest the shocking nature of the crime induce an instinctive reaction against dispassionate judicial scrutiny of the facts and law”.
