Intent often matters in the law (aside from certain laws with strict liability). You intentionally drive your car into someone you hate and kill them => murder, go straight to jail. You're driving along normally and someone who's chasing their pet cat suddenly runs into traffic and you hit them => no charges. Sometimes you can be charged with negligence for not taking enough care to prevent something, but then you have to deal with the tricky question of how much care is enough.
