Tahalliset

Tahalliset is a Finnish term used as an adjective meaning deliberate or intentional; in plural form it is used as a noun to refer to intentional acts or wrongdoing. It denotes actions performed with purpose, will, or acceptance of the likely consequences.

In everyday language, tahallisesti means “on purpose” and tahallinen teko means “an intentional act.” It contrasts with satunnainen (accidental) and with tuottamuksellinen (negligent). In ethics and philosophy, tahallisuus refers to the agent's mental state regarding outcomes.

In Finnish law, tahallisuus is a central mens rea element; crimes may be classified as tahallisia if the offender intends the result or accepts the risk. There are distinctions between direct intent (the person aims to bring about a harmful result) and indirect or oblique intent (the person foresees the harm and continues anyway). The presence and degree of tahallisuus influence liability and penalties, and some offenses can be established only through evidence of intent, while others allow liability for negligent actions as well.

Because the term is used across contexts, tahalliset may appear in legal documents, criminology discussions, and media reports on deliberate wrongdoing.
