Attempts to Commit Offences
When an abetted act causes a different effect than the abettor intended, the abettor is liable for the actual effect caused, in the same manner as if they'd intended that effect - provided they knew the abetted act was likely to cause it.
If your abetment leads to a worse outcome than you specifically intended, but one you knew was a realistic possibility, you're held liable for that worse actual outcome, not let off the hook just because it wasn't precisely what you set out to achieve.
Someone who instigates another to cause grievous hurt to a victim, knowing that death is a likely possible result, is liable for murder if the victim actually dies - even though grievous hurt (not death specifically) was the originally intended effect.
