My Wife's Baby

Does the love for a wife and the jealousy for an infant, warrant murder?

After ten years of bad dates and worse relationships, Stan is in heaven, for he has finally found his soul mate, Erica€"a beautiful, caring woman who shares all his beliefs, to include not wanting children. They discussed this over bottles of red wine the night they met and promised, if ever they became a couple, they would remain childless and forever the other€s priority.
One year after being married, Erica tells Stan she€s pregnant: news she€s very happy about. Stan considers talking Erica out of it, but that would mean aborting her child, something he knows Erica would never do.
Two months into the pregnancy, Stan notices changes: times he and Erica enjoyed as a fun-loving childless couple are no longer; Erica€s attention is occupied with all things related to the forthcoming baby, and Stan has gone without sex for months.
The child arrives and things get even worse; Stan feels like an outsider: a stranger living among his wife and her son. Erica gives all her time, attention and love to the infant, leaving none for her husband. Stan becomes envious; he looks at the newborn as a threat, tells himself something must be done€"but what? He fights his jealous thoughts, knowing horrible things would happen if he were ever to act on them. But one night while drunk, Stan attempts to make love to his wife but is once again rejected. His pride hurt and feeling disowned, Stan stumbles into the baby€s room with intentions of eliminating his problem once and for all, knowing there can only be one man in Erica€s life. That is the promise his wife had made him on the night they met, and it is the promise he intends to make her keep.
